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
Answer: 8 , 60 , 23.3
Step-by-step explanation: 2/3 x 12 = 8
3 of 20 = 60
10/9 x 21 = 70/3 = 23.3
