Find the length (s) of one side of the square:

ft.
With this information, you can now find the area of the square (A):

square ft.
---------------------
You are given enough information to find the area of the circle (B):

square feet.
---------------------
Finally, to get the area inside the square but outside the circle, just subtract the area of the circle from the area of the square:
