Answer 2

• 31.625 ft²

Explanation:

• It is assumed we need to find the area of shaded figure.

The figure comprises of two semicircles and a triangle.

The two semicircles add to one full circle with the diameter of 5 ft.

Area of circle

• A = πr² = 3.14*(5/2)² = 19.625 ft²

Area of triangle

• A = 1/2bh = 1/2(6)(4) = 12 ft²

Total area

• 19.625 + 12 = 31.625 ft²
