Answer:
E) 30.3 m^2
Explanation:
First, find the area of the trapezoid, which is (a+b )h/2, or base 1 plus base 2 times height divided by 2. Solving, this gives you (2+10)4/2, or 24 m^2.
Next, find the area of the semicircle which is 1/2*pi*r^2, where r=d/2. Plugging this in, 1/2*pi*(4/2)^2 gives you about 6.3 m^2.
Adding, 24+6.3=30.3 m^2.
