You can put this solution on YOUR website!
If the length of the side of that square pool (in feet is x.
the area of the pool (in square feet) is x%5E2
x%5E2=196
The positive solution is x=14
If you add 8 feet left and right, the total length of the deck (in feet) will be
14%2B8%2B8=30
The pool plus deck will be a square with a side length of 30 feet.
The perimeter (in feet) is
4%2A30=120
The outside perimeter of the deck is 120 feet.
