Step 1) Use the area formula to find the length of the radius

A = (3.14 x r^2) / 4

3.14 = (3.14 x r^2) / 4

12.56 = 3.14r^2

r^2 = 4

r = 2 feet

Step 2) Use the perimeter formula to find the perimeter

C = ((pi x 2r) / 4) + 2r

C = ((3.14 x 4) / 4) + 4

C = (12.56 / 4) + 4

C = 3.14 + 4

C = 7.14 feet

Hope this helps! :)
