Answer:

24+6pi

Step-by-step explanation:

the sides on the left and right added up are

12+12=24.

the formula for perimeter of a circle is 2πr.

3 is the radius, making the equation

2π3 which is 6 pi.

for the top semicircle, the perimeter would be 6 pi divided by 2 because its a semicircle.

the bottom cut out half would also be 3 pi.

in total, we would have 24+3pi+3pi which would lead you to 24+6pi.
