Problema Solution

The area of a square is 5 more than the perimeter. Find the length of the side.

Answer provided by our tutors

let 'x' represent the side of the square


area = x*x

perimeter = 4x


solve for the side:

xx = 5 + 4x

-----------------------------

solve for 'x'

-----------------------------

x = {5, -1}


The side of the square is 5 since a negative length is ignored.
