Question 619210
 A square's side is increased by 2 yards, which corresponds to an increase in the area by 36 square yards. How many yards is the side of the initial square?
------------
The original side = s
The original area = s^2
----
{{{(s+2)^2 = s^2 + 36}}}
{{{s^2 + 4s + 4 = s^2 + 36}}}
4s + 4 = 36
s = 8
