Answer:

86.28 ft²

Step-by-step explanation:

The figure given consists of a rectangle and a semicircle. The area of the figure = area of rectangle + area of semicircle

Area of rectangle =

Where,

l = 10 ft

w = 8 ft

Area of semicircle:

Area of semicircle = ½ of area of a circle = ½(πr²)

Where,

π = 3.14

r = ½ of 8 = 4 ft

Area of semi-circle = ½(3.14*4) = 6.28 ft²

Area of the figure = area of rectangle + area of semi-circle = 80 + 6.28 = 86.28 ft² (nearest hundredth)
