Quiz Matematika Kelas 4

The correct answer is "Tumpul, lancip dan siku-siku." This is because the question is asking for the three types of angles, and "tumpul" means obtuse, "lancip" means acute, and "siku-siku" means right angle. Therefore, the answer includes all three types of angles: obtuse, acute, and right angle.

A penggaris is a measuring tool specifically used to measure length or distance. It is a straight, flat, and narrow strip of material with marked units of measurement, usually in centimeters or inches. A penggaris is commonly used in various fields such as mathematics, engineering, and design to accurately measure the length of objects or draw straight lines.

The correct answer is kg because kg is the unit commonly used to measure the weight of rice. Hg, dg, and g are not commonly used for measuring the weight of rice.

The correct answer is 16. The question states that Ayah will make a room for his sibling with dimensions of 4 m x 4 m. To find the area of the room, we multiply the length and width, which in this case is 4 m x 4 m = 16 square meters.

The given numbers 20, 12, 18, and 16 are the lengths of the sides of a triangle. To calculate the perimeter or the total length of the sides of the triangle, we add up these numbers. Adding 20, 12, 18, and 16 gives us a total of 66. Therefore, the perimeter or the length of the sides of the triangle is 66.

The given answer, "125 cm dan 2 mm," is correct because when rounding a measurement, we usually round to the nearest whole unit. In this case, the original length of the ribbon was 125 cm, and when rounded, it remains the same. The additional 2 mm is not significant enough to affect the overall length, so it can be ignored. Therefore, the length of the ribbon before rounding is still 125 cm.

The correct answer is 78 because the perimeter of an equilateral triangle is equal to the sum of the lengths of its three sides. Since all sides of the equilateral triangle are equal, each side must be 26 cm. Therefore, the perimeter of the triangle is 26 + 26 + 26 = 78 cm.

The given options represent different ways to express negative 17. The symbol "-" indicates a negative number, and "17" represents the absolute value of the number. Therefore, the correct answer is -17, which means negative 17.

The perimeter or keliling of a rectangular pool can be calculated by adding the lengths of all four sides. In this case, the length is 88 cm and the width is 22 cm. So, the perimeter would be 2 * (88 + 22) = 220 cm.

The formula to calculate the area of a triangle is 1/2 * base * height. In this case, the base of the triangle is 24 cm and the height is 18 cm. Plugging these values into the formula, we get 1/2 * 24 * 18 = 216 cm². Therefore, the correct answer is 216.

The given question states that an object is measured with a ruler and the result is 3.4 cm. The question then asks what the result would be if it is rounded. Since the decimal part is less than 0.5, the general rule of rounding is to round down. Therefore, the correct answer is 3 cm.

The correct answer is 2.000 m. The question states that the distance from Bagas's house to school is 2 Km. Since 1 Km is equal to 1,000 m, we can convert the distance to meters by multiplying 2 Km by 1,000. Therefore, the distance from Bagas's house to school is 2,000 m.

The correct answer is "Segi banyak beraturan dan segi banyak tidak beraturan". This answer correctly identifies the two types of polygons, which are regular polygons (beraturan) and irregular polygons (tidak beraturan). Regular polygons have all sides and angles equal, while irregular polygons have sides and angles that are not equal.

A polygon with five sides of equal length is called a pentagon.

The perimeter of a triangle is found by adding up the lengths of all its sides. In this case, the lengths of the sides are 4.5 cm, 7.5 cm, and 5.5 cm. Adding these lengths together, we get 4.5 + 7.5 + 5.5 = 17.5 cm. Therefore, the correct answer is 17.5 cm.

The answer "Sama besar" means "the same weight" in English. This suggests that the weight of the iron and the weight of the cotton are equal when they both weigh 1 kg.

Satuan panjang yang digunakan sebagai satuan jarak adalah kilometer (km). Kilometer adalah satuan panjang yang digunakan untuk mengukur jarak yang lebih jauh. Satuan ini sering digunakan dalam pengukuran jarak antar kota atau negara. Centimeter (cm), meter (m), dan decimeter (dm) adalah satuan panjang yang lebih kecil dan biasanya digunakan untuk pengukuran jarak yang lebih pendek.

The unit of length commonly used to measure the length of clothing is meter.

The area of a rectangle can be found by multiplying its length by its width. In this case, the length of the rectangle is given as 28 cm and the width is given as 9 cm. Therefore, the area of the rectangle is 28 cm * 9 cm = 252 cm².

Segibanyak adalah istilah yang tidak dikenal dalam matematika. Namun, jika kita mengasumsikan bahwa itu adalah kesalahan penulisan dan seharusnya menjadi "segitiga", maka segitiga memiliki banyak sudut dan banyak sisi. Segitiga memiliki tiga sudut dan tiga sisi.

The correct answer is "Bilangan bulat positif, nol dan bilangan bulat negatif". This is because the definition of bilangan bulat (integer) includes positive integers, zero, and negative integers.

The given options represent different types of triangles based on their angles. "Segitiga sama kaki" refers to an isosceles triangle where two sides are equal. "Segitiga tumpul" refers to an obtuse triangle where one angle is greater than 90 degrees. "Segitiga siku-siku" refers to a right triangle where one angle is 90 degrees. "Segitiga lancip" refers to an acute triangle where all angles are less than 90 degrees. Therefore, the correct answer is "Segitiga sama kaki" as it is the only option that does not describe a triangle based on its angles.

The given equation involves converting different units of measurement to meters. First, 20.000 cm is converted to meters by dividing by 100, resulting in 0.200 m. Then, 3.000 mg is converted to grams by dividing by 1000, resulting in 0.003 g. Finally, 200 dm is converted to meters by multiplying by 10, resulting in 2000 m. Adding these values together, we get 0.200 m + 0.003 g + 2000 m = 2000.203 m. Rounding to the nearest whole number, the answer is 2000 m, which is closest to 2170.

The formula to calculate the perimeter of a square is 4 times the length of one side. In this case, the length of one side is given as 48 cm. Therefore, the perimeter of the square can be calculated as 4 * 48 = 192 cm.

The given sequence of numbers is arranged in descending order. Starting with the largest number, 10, the sequence is followed by 8, 6, -7, and finally -9.

The given statement states that there are three coconuts, each weighing 1.3 kg. To round off the result, we need to find the total weight of the three coconuts. Since each coconut weighs 1.3 kg, the total weight of the coconuts would be 3.9 kg. When rounding off to the nearest whole number, 3.9 kg would be rounded up to 4 kg. Thus, the correct answer is 4 kg.

The correct answer is "Oktagon" because an oktagon is a regular polygon with eight equal sides and eight equal angles. In the given statement, it is mentioned that the polygon has sides and angles of the same size, which fits the definition of an oktagon.

The correct answer is 3.990. To solve the equation, we need to convert all the units to the same unit. Since we want the answer in meters, we need to convert 30 meters to meters, 40 Hm to meters, and 4,000 cm to meters. 1 Hm is equal to 100 meters, so 40 Hm is equal to 4,000 meters. 1 cm is equal to 0.01 meters, so 4,000 cm is equal to 40 meters. Adding all the converted values, we get 30 + 4,000 + 40 = 4,070 meters. However, the answer choices do not include this value, so the closest option is 3.990 meters.

The correct answer is "Neraca." The given options are "Neraca ohaous," "Neraca," "timbangan," and "penggaris." Based on the options provided, the picture below is most likely a "Neraca," which is a weighing scale used to measure the weight or mass of an object.

The given answer is correct because it correctly states the formulas for finding the area (Luas) and perimeter (Keliling) of a rectangle. The formula for finding the area of a rectangle is length (p) multiplied by width (l), and the formula for finding the perimeter is 2 multiplied by the sum of the length and width. Therefore, L = p x l and K = 2 x (p + l) is the correct answer.
