If the size of the square are lengthened by 5 cm, the area become 196 cm^2. find the length of a side of the original square
-----------------
Original side: x
Original Area: x^2
-------------
New side: x+5
New Area:(x+5)^2
----
Equation:
(x+5)^2 = 196 cm^2
---
x+5 = 14
x = 9 cm (side of original square)
