Answer:

592.83 ft^2

Step-by-step explanation:

First estimate the area of the rectangle:

Area rectangle = Base x Height = 20 * 36 = 720 ft^2

and then subtract from it the area of a semi-circle of radius 18/2 = 9 ft

Using the formula for the semicircle's area:

Semi-circle's area= pi * R^2 / 2 = 3.14 * 9^2 / 2 = 127.17 ft^2

Such gives us:

720 ft^2 - 127.17 ft^2 = 592.83 ft^2
