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
-----------------------------
-----------------------------
x = {5, -1}
The side of the square is 5 since a negative length is ignored.
