Answer:
Step-by-step explanation:
you can figure out the area by using two formulas: area of a circle (on each end are two semi circles which when combined, make a circle) and area of a rectangle
Acircle: pi(r^2) = pi(5^2) = 25pi
Arectangle: length*width = 20*10 = 200ft^2
area of composite figure: (25pi ft^2) + 200ft^2
