Jarak rumah Bagas ke sekolah adalah 2 Km. Jarak itu sama juga dengan ….
- A.
200 m
- B.
20 m
- C.
2.000 m
- D.
20.000 m
Correct Answer
C. 2.000 mExplanation
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.Rate this question:

Hasil dari 30 m + 40 Hm – 4.000 cm = …. m
- A.
4.340
- B.
3.940
- C.
30
- D.
3.990
Correct Answer
D. 3.990Explanation
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.Rate this question:

20.000 cm – 3.000 mg + 200 dm = …. m
- A.
197
- B.
207
- C.
217
- D.
2170
Correct Answer
C. 217Explanation
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.Rate this question:

Panjang sebuah pita adalah 125 cm setelah dibulatkan . Kira-kira berapa panjang pita sebelum dibulatkan
- A.
125 cm dan 2 mm
- B.
125 cm dan 6 mm
- C.
125 cm dan 7 mm
- D.
125 cm dan 9 mm
Correct Answer
A. 125 cm dan 2 mmExplanation
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.Rate this question:

- A.
3 kg
- B.
4 kg
- C.
5 kg
- D.
6 kg
Correct Answer
B. 4 kgExplanation
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.Rate this question:

Rumus luas dan keliling persegi panjang adalah ....
- A.
L = s x s dan K = 4 x s
- B.
L = p x l dan K = 2 x p x l
- C.
L = p + l dan K = 2 x (p + l)
- D.
L = p x l dan K = 2 x (p + l)
Correct Answer
D. L = p x l dan K = 2 x (p + l)Explanation
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.Rate this question:
