Answer:
=439.04 ft^2
Step-by-step explanation:
First find the area of the total rectangle
A = l*w
40*16 =640 ft^2
We have 2 semi circles with diameter 16
That equals 1 circle with diameter 16
The radius is d/2 = 16/2 =8
The area of a circle is
A = pi r^2
A = (3.14) (8)^2
=200.96
Subtract the unshaded area from the total area
640-200.96=439.04
