A rectangular classroom is 12 m long and 7.5 m wide. What is its area?
Answer: 90 m²
Area = length × width = 12 × 7.5 = 90 m².
A school excursion walk is 2.5 km. How many metres is this?
Answer: 2500 m
1 km = 1000 m, so 2.5 × 1000 = 2500 m.
Two angles of a triangle measure 52° and 68°. What is the third angle?
Answer: 60°
The angles in a triangle sum to 180°. 52 + 68 = 120, and 180 − 120 = 60°.
A circle has a radius of 5 cm. Using π ≈ 3.14, what is its approximate circumference?
Answer: 31.4 cm
Circumference = 2πr = 2 × 3.14 × 5 = 31.4 cm. 78.5 cm is the area.
A rectangular prism measures 4 cm by 5 cm by 3 cm. What is its volume?
Answer: 60 cm³
Volume = length × width × height = 4 × 5 × 3 = 60 cm³.
A lesson starts at 9:45 am and lasts 2 hours 50 minutes. When does it finish?
Answer: 12:35 pm
9:45 am + 2 hours = 11:45 am, and a further 50 minutes gives 12:35 pm.
