Answer:

60.84 m

Step-by-step 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
