Answer:

50.26 if you use 3.14 for pi

50.35 if you use 3.15 for pi

Explanation:

First, we find the circumference of the circle in the center.

(15 - 3 - 3)/2 = 4.5

4.5 is the radius

Equation for circumference: 2*pi*r

2*pi*4.5

9pi

Depending on where you normally use 3.14 or 3.15 for pi changes the answer but for this example I will use 3.14

The circumference of the circle is 28.26

Next, add the other sides of the figure.

28.26 + 3 + 3 + 3 + 3 + 5 + 5 = 50.26
