The length of a line is 6 centimetres (cm). How many millimetres (mm) is it?
Correct Answer
B. 60mm
Explanation
Since there are 10 millimeters in 1 centimeter, to convert centimeters to millimeters, we need to multiply the length by 10. Therefore, 6 centimeters is equal to 60 millimeters.
2.
A length of a line is 5 metres (m). How many centimetres (cm) is it?
Correct Answer
A. 500cm
Explanation
The length of a line is given as 5 meters. To convert meters to centimeters, we need to multiply the length by 100 since there are 100 centimeters in 1 meter. Therefore, 5 meters is equal to 500 centimeters.

5.
What is the area of this rectangle?(each square is 1cm squared)
Correct Answer
B. 12cm squared
6.
Which two shapes have the same area but different perimeters?
Correct Answer
A. Figure 1 & figure 4
Explanation
Figure 1 and figure 4 have the same area but different perimeters because they have different shapes. The area of a shape is determined by the amount of space it occupies, while the perimeter is the total length of its boundary. Even though figure 1 and figure 4 may have the same area, their perimeters will be different because their shapes are not the same.
7.
What is the area of this irregular shape?
Correct Answer
C. 46cm squared
Explanation
The correct answer is 46cm squared because it is the only option that represents the area of the irregular shape. The other options, 15cm and 42cm squared, do not provide a measurement of area.
8.
Find the area of this triangle.(Remember: A= 1/2 base x height)
Correct Answer
A. 33cm squared
Explanation
To find the area of a triangle, we can use the formula A = 1/2 base x height. In this case, the correct answer is 33cm squared. This means that the base and height of the triangle must be such that when multiplied together and divided by 2, the result is 33cm squared. Without further information, we cannot determine the specific values of the base and height, but we know that their product is 66cm squared, and when divided by 2, it gives us the correct answer of 33cm squared.

5 cm = 50 mm
Correct Answer
A. True
Explanation
The statement "5 cm = 50 mm" is true because there are 10 millimeters in 1 centimeter. Therefore, if we multiply 5 centimeters by 10, we get 50 millimeters.
10.
7 m = 70 cm
Correct Answer
B. False
Explanation
The statement "7 m = 70 cm" is false. This is because 1 meter is equal to 100 centimeters. Therefore, 7 meters would be equal to 700 centimeters, not 70 centimeters.
11.
1 g = 1000 mg
Correct Answer
A. True
Explanation
The statement "1 g = 1000 mg" is true because it is a conversion factor between grams and milligrams. It means that one gram is equal to one thousand milligrams. This is a commonly used conversion in the metric system, where milligrams are a smaller unit of measurement compared to grams.
12.
5 kg = 500 g
Correct Answer
B. False
Explanation
The statement "5 kg = 500 g" is false. 5 kg is equal to 5000 g, not 500 g. The conversion from kilograms to grams involves multiplying the weight in kilograms by 1000, so 5 kg would be equal to 5000 g. Therefore, the correct answer is False.
13.
3 L = 3000 mL
Correct Answer
A. True
Explanation
The given statement is true because 1 liter (L) is equal to 1000 milliliters (mL), so if we have 3 liters, it would be equal to 3000 milliliters. Therefore, the statement "3 L = 3000 mL" is correct.
14.
9 m = 100 mm
Correct Answer
B. False
Explanation
The given statement "9 m = 100 mm" is false. This is because 9 meters is equal to 9000 millimeters, not 100 millimeters. Therefore, the correct answer is False.
15.
50 cm = 500 mm
Correct Answer
A. True
Explanation
The statement is true because 1 cm is equal to 10 mm. Therefore, if we have 50 cm, we can convert it to mm by multiplying it by 10. This gives us 500 mm, which means that 50 cm is indeed equal to 500 mm.
16.
37 L = 37000 mL
Correct Answer
A. True
Explanation
The given statement states that 37 liters is equal to 37000 milliliters. This is true because there are 1000 milliliters in 1 liter. Therefore, to convert liters to milliliters, we multiply the number of liters by 1000. In this case, 37 liters multiplied by 1000 equals 37000 milliliters. Hence, the statement is true.
17.
5 m = 5000 cm
Correct Answer
B. False
Explanation
The statement "5 m = 5000 cm" is true because 1 meter is equal to 100 centimeters. Therefore, multiplying 5 meters by 100 gives us 500 centimeters, not 5000 centimeters. Hence, the correct answer is False.
18.
7 L = 70 mL
Correct Answer
B. False
Explanation
The statement "7 L = 70 mL" is false. This is because 1 liter (L) is equal to 1000 milliliters (mL), not 10 mL. Therefore, 7 L would actually be equal to 7000 mL, not 70 mL.
19.
5 kg = 5000 g
Correct Answer
A. True
Explanation
The conversion from kilograms to grams is done by multiplying the weight in kilograms by 1000. Since 1 kilogram is equal to 1000 grams, 5 kilograms would be equal to 5000 grams. Therefore, the statement "5 kg = 5000 g" is true.
