LLN Geometry and Spatial Reasoning

Question 1

A rectangular room is 12 m long and 7 m wide. What is its area?

Accepted Answer

84 m²

Answer

Area of a rectangle = length × width = 12 × 7 = 84 m².

Question 2

Two angles of a triangle measure 55° and 65°. What is the third angle?

Accepted Answer

60°

Answer

The angles in a triangle sum to 180°. 55 + 65 = 120, and 180 − 120 = 60°.

Question 3

A circle has a radius of 5 cm. Using π ≈ 3.14, what is its circumference?

Accepted Answer

31.4 cm

Answer

Circumference = 2πr = 2 × 3.14 × 5 = 31.4 cm.

Question 4

A box measures 4 cm by 5 cm by 3 cm. What is its volume?

Accepted Answer

60 cm³

Answer

Volume of a rectangular prism = length × width × height = 4 × 5 × 3 = 60 cm³.

Question 5

A right-angled triangle has shorter sides of 6 cm and 8 cm. How long is the hypotenuse?

Accepted Answer

10 cm

Answer

By Pythagoras' theorem, c² = 6² + 8² = 36 + 64 = 100, so c = 10 cm.
