WAEC Agricultural Science 2025 Objective — Question 28

Question 28 of 50 from the West African Examinations Council (WAEC) Agricultural Science 2025 Objective paper, with the correct answer and a full explanation.

A farmland was surveyed and mapped as shown in the diagram below. If AB is 15m, DC is 10m and EF is 8m, calculate the area of the farmland

• A. 80m²
• B. 100m²Correct
• C. 120m²
• D. 200m²

Explanation

Since the farmland is shaped like a trapezium, area = 1/2(a+b) x h, where a = DC = 10m, b = AB = 15m, h = EF = 8m. Thus, area = 1/2(10+15) x 8 = 100m².
