Answer:
60.84 m
Explanation:
The perimeter is the distance around
The distance around the 3 sides of the rectangle are
15+12+15
42
Now we are going 1/2 way around the circle
That is 1/2 of the circumference
1/2 C = 1/2 pi *d
= 1/2 pi *12
= 6pi
Using 3.14 for pi
= 6 (3.14)
=18.84
Add these together
42+18.84
60.84 m
