Question 1037063

If one side of a square is 15 feet less than the perimeter,find the length of a side of the square.
<pre>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 = {{{(- 15)/(-3)}}}, or {{{highlight_green(matrix(1,2, 5, feet))}}}
