Answer:
A = 119.25ft²
Step-by-step explanation:
Area of a rectange: [tex]A = wl[/tex]
Area of a circle: [tex]A = \pi r^{2}[/tex]
A₁ = 8 x 10 = 80ft²
A₁ being the rectangle in the image
With approximatting π to be 3.14,
r = 10 / 2 = 5ft
A₂ = π5² = 78.5ft²
Now since it's half a circle, we divide the area by 2,
A₂ = 39.25ft²
A = A₁ + A₂
