Question

brookes swimming pool is shown in the image below. what is the area of brookes swimming pool? (with a diagram of a blue - colored swimming pool - like figure, with side length markings: 10m, 10m, 3m, 2m, 4m)

Explanation:

Step1: Calculate area of large rectangle

Area = length × width = $10×10 = 100$ m²

Step2: Calculate area of missing trapezoid

Area = $\frac{1}{2}×(a+b)×h = \frac{1}{2}×(2+3)×4 = 10$ m²

Step3: Subtract missing area from rectangle

Total area = $100 - 10 = 90$ m²

Answer:

90 m²
