Bagus mempunyai 3 tali, panjang masing-masing tali adalah 200 cm, 3 m dan 40 dm. Panjang seluruhnya dari ketiga tali tersebut adalah .... m.

• A.

63 m

• B.

9 m

• C.

123 m

• D.

243 m

B. 9 m
Explanation
The question asks for the total length of the three ropes in meters. To find the total length, we need to convert the lengths of the ropes to the same unit. Since 1 m = 100 cm, we can convert the first rope's length to meters by dividing 200 cm by 100, which equals 2 m. The second rope is already given in meters. To convert the third rope's length to meters, we need to convert 40 dm to cm by multiplying it by 10, which equals 400 cm. Then, we divide 400 cm by 100 to get 4 m. Adding up the lengths of the three ropes (2 m + 3 m + 4 m) gives us a total of 9 m.

4 Kg + 30 Ons + 1 Kuintal = .....kg

• A.

103 Kg

• B.

105 Kg

• C.

8 Kg

• D.

107 Kg

D. 107 Kg
Explanation
The given question asks to find the sum of 4 kg, 30 ons, and 1 kuintal in kg. To solve this, we need to convert the ons and kuintal to kg. There are 10 ons in 1 kg, so 30 ons is equal to 30/10 = 3 kg. Similarly, there are 100 kg in 1 kuintal, so 1 kuintal is equal to 100 kg. Adding all the values together, we get 4 kg + 3 kg + 100 kg = 107 kg. Therefore, the correct answer is 107 kg.

• A.

160

• B.

165

• C.

26

• D.

52

B. 165
Explanation
The area of a parallelogram is calculated by multiplying the length of the base (alas) by the height (tinggi). In this case, the base is 11 cm and the height is 15 cm. Therefore, the area is 11 cm x 15 cm = 165 cm².

Rate this question:

Sebuah jajar genjang memiliki luas 340 cm² dan tingginya adalah 17 cm. Maka alasnya adalah ....

• A.

10 cm

• B.

40 cm

• C.

20 cm

• D.

30 cm

C. 20 cm
Explanation
The area of a parallelogram is calculated by multiplying the base (alas) by the height (tinggi). In this case, the area is given as 340 cm² and the height is 17 cm. To find the base, we can rearrange the formula and divide the area by the height: base = area / height. Therefore, the base is 340 cm² / 17 cm = 20 cm. Hence, the correct answer is 20 cm.

Rate this question:

Jika luas bangun di atas adalah 475 cm² maka tingginya adalah ....

• A.

15 cm

• B.

39 cm

• C.

19 cm

• D.

17 cm

C. 19 cm
Explanation
The correct answer is 19 cm. This can be determined by using the formula for finding the area of a rectangle, which is length multiplied by width. Since the area is given as 475 cm², and the width is not provided, it is not possible to calculate the exact dimensions of the rectangle. However, by using the given answer options, we can determine that the height must be 19 cm in order for the area to be 475 cm².

Rumus untuk mencari luas segitiga adalah ....

• A.

A x t x 2

• B.

A + t x 2

• C.

A x t : 2

• D.

A x t + 2

C. A x t : 2
Explanation
The formula to find the area of a triangle is given by multiplying the base (a) and the height (t), and then dividing the product by 2. This formula is derived from the fact that the area of a triangle is equal to half the product of its base and height. Therefore, the correct answer is a x t : 2.

Rate this question:

• 24.

Luas sebuah segitiga yang panjang alasnya 21 cm dan tinggi 15 cm adalah ....

• A.

215 cm²

• B.

325,5 cm²

• C.

315 cm²

• D.

157,5 cm²

D. 157,5 cm²
Explanation
The correct answer is 157,5 cm². To find the area of a triangle, you can use the formula: Area = (base x height) / 2. In this case, the base is 21 cm and the height is 15 cm. Plugging these values into the formula, we get: Area = (21 cm x 15 cm) / 2 = 315 cm² / 2 = 157,5 cm².

Rate this question:

• 25.

Jika sebuah segitiga mempunyai luas 200 cm² dan tingginya adalah 10 cm. Maka panjang alas segitiga tersebut adalah ....

• A.

30 cm

• B.

40 cm

• C.

50 cm

• D.

60 cm

B. 40 cm
Explanation
The area of a triangle is equal to half the product of its base and height. In this case, the area is given as 200 cm² and the height is given as 10 cm. Therefore, we can use the formula A = (1/2) * b * h to find the length of the base. Rearranging the formula, we get b = (2 * A) / h. Substituting the given values, we get b = (2 * 200) / 10 = 40 cm. Therefore, the length of the base of the triangle is 40 cm.
