WebLet's break the area into two parts: Part A is a square: Area of A = a 2 = 20m × 20m = 400m 2. Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m. Area of B = ½b × h = ½ × 20m × 14m = 140m 2. So the total area is: Area = Area of A + Area of B = 400m 2 + 140m 2 = 540m 2. Sam earns $0.10 per square meter.
