Question 184289
The area of a square is numerically 3 less than the perimeter.
 Find the length of the side, if this length is greater than 1 unit.
:
Let s = length of a side
then
s^2 = area
;
s^2 = 4s - 3
:
s^2 - 4s + 3 = 0
Factor
(s-3)(s-1) = 0
Greater than 1 solution
s = 3 units

Check: 3^2 = 4(3) - 3
