Answer:

57.72 ft²

Step-by-step explanation:

Find the area of a semicircle with radius 2 ft.  Subtract this from the area of a triangle with base 8 ft and height 4 ft.  Add this to the area of a rectangle with width 6 ft and length 8 ft.

Area of semicircle = [tex]\dfrac12\pi r^2=\dfrac12 \times 3.14 \times 2^2=6.28[/tex]

Area of triangle = [tex]\dfrac12 \times base \times height=\dfrac12 \times 8 \times 4=16[/tex]

Area of rectangle = width x height = 6 x 8 = 48

Total area = (16 - 6.28) + 48 = 57.72 ft²
