Answer:
A = 586.08 ft²
Solution:
A = LW + 3.14(r)²/2
A = (24 ft ×15 ft) + 3.14(12 ft)²/2
A = 360 ft² + 226.08 ft²
A = 586.08 ft²
Maybe you are surprised where i get the 12 ft.
It is from the 1/2 (24ft), as you see in the figure the length is 24 ft which is also the diameter of the semicircle. So to solve for the radius it is the half of the diameter thats why the radius is 12 ft.
