If one side of a square is 15 feet less than the perimeter,find the length of a side of the square.
Let one side of square, be S

Then perimeter = 4S

We then get: S = 4S - 15

S - 4S = - 15

- 3S = - 15

S, or a side of the square = %28-+15%29%2F%28-3%29, or highlight_green%28matrix%281%2C2%2C+5%2C+feet%29%29
