Step-by-step explanation:
There are four quarter circles, each with radius 9 ft. Together, they form a full circle. There are also four squares, each with side length 9 ft.
A = πr² + 4s²
A = π (9 ft)² + 4 (9 ft)²
A ≈ 578.469 ft²
The actual height is: 1 1/2 * 2 = 3 feet
The actual length is: 5 1/8 * 2 = 10.25 feet
