The question, in short
Find the least number of 12 m² paint tins needed to paint a trapezium-shaped wall twice, using parallel sides 2.5 m and 3.5 m and base 6.5 m; show working.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 4 marks
- 1Area of wall = ½ × (2.5 + 3.5) × 6.5 = 19.5 m²
- 2Painted twice: 2 × 19.5 = 39 m²
- 339 ÷ 12 = 3.25 tins, so round up to 4
