Answer:
39.53 ft^2
Step-by-step explanation:
We can find the area of the rectangle
A = l*w
= 12*3 = 36
And the area of the semicircle
A = 1/2 pir^2
The diameter is 3, the radius is 3/2
=1/2 pi* (3/2)^2
= 1/2 *3.14 * 9/4
3.5325
Add the two areas together
36+3.532539.5325
Rounding to the nearest hundredth
39.53 ft^2
