The image shows a square with a circle cut out of it.
We need to compute the area of the square and subtract the area of the circle to find the shaded area.
The area of a square of side length x is:

We are given the side length of x = 10 ft, thus:

The area of a circle of radius r is given by:

The circle inside the square has a diameter of d=10 ft, thus its radius is r = 10/2 = 5 ft. Calculating the area:

Using π=3.14:

Now, subtracting areas:

Rounding to the next integer, the required area is approximately 22 square ft
Choice: 22 square ft
