Sample questions
Question 1 — Easy
Tom is painting a triangular mural on a wall. The triangle has a base of 14 m and a height of 6 m. Use the formula for the area of a triangle to find its area.
Answer: The area of a triangle is A = ½ × base × height = ½ × 14 × 6 = 42 m². Option A forgets the ½ and gives base × height. Option C adds the base and height. Option D uses an incorrect calculation of ½ × base × height with a different height.
Question 2 — Medium
A triangular garden bed has a base of 8 m and a height of 5 m. Calculate the area of the garden bed.
Answer: The formula for the area of a triangle is A = ½ × base × height. Substituting the values: A = ½ × 8 × 5 = 20 m². Option A forgets to halve the product. Options C and D result from adding or doubling the dimensions incorrectly.
Question 3 — Hard
A parallelogram-shaped tile has a base of 10 cm and a height of 6 cm. What is the area of the tile?
Answer: The formula for the area of a parallelogram is A = base × height. Substituting: A = 10 × 6 = 60 square centimetres. Option A halves the result, confusing this with the triangle formula. Options B and C result from adding the dimensions.
