CAAT Measurement and Units 3

Question 1

A rectangle has a perimeter of 24 cm and a length of 8 cm. What is its width?

Accepted Answer

4 cm

Answer

Perimeter = 2(length + width), so 24 = 2(8 + w), giving 12 = 8 + w, so w = 4 cm.

Question 2

Which unit is most appropriate for measuring the distance between two cities?

Accepted Answer

Kilometers

Answer

Kilometers are used to express large distances like those between cities, giving practical numbers rather than very large or very small values.

Question 3

A container holds 750 mL of juice. If you pour out 250 mL, how much remains?

Answer

750 mL − 250 mL = 500 mL remaining in the container.
