Answer:

12.6

Step-by-step explanation:

We can start by finding the area of the rectangle

13x4=52

Now the semicircles, the diameter of the circle is 4, so the radius is 2 to find the area we do

pi x 2=6.3

6.28^2=39.4

since there are two circles we can just add them together instead of dividing the answer above by 2, now we can subtract this from 52

52-39.4=12.6
