To find the area of the figure, split it into two regular shapes: a rectangle and a semi-circle. Find the area of each and add it together.

Area of the rectangle is A = 8*10 = 80 square feet.

Are of semicircle is A = 1/2 πr² = 1/2 (3.1)(4²) = 1/2(3.1)(16) = 24.8 square feet.

Together the area is 80 + 24.8 = 104.8 square feet
