Square side=40ft
Semi-circle diameter=39.98ft
Area of court=2276.69 ft^2
Step-by-step explanation:
The square section has a semicircle joined to it and the combined perimeter is 182.8 ft.
-Area of the square section is obtained by subtracting that of the semicircle from the total(only 3 sides of the square is used since one side is attached to the semi-circle)
Hence, the square's sides has the dimension of 40 ft.
The semi-circle's diameter is calculated as:
Hence, the semi-circle's diameter is 39.98 ft
The area of the court is calculated as:
The court's area is 2,227.69 ft^2
