A square pool has a 6-foot wide walk around it. If the sides of the pool have length x, find a polynomial that gives the area of the pool and sidewalk.

Let one side of square be S
Then area of pool =
As a uniform width of 6 feet adds 12 (6 * 2) feet to each side of the pool, area of pool and sidewalk is:
