The length of a rectangle is 9 more than the width. The area is 162 square yards. Find the length and width of the rectangle.
------------
Find a pair of factors of 162 that differ by 9.
---
Or,
L*W = 162
L = W + 9
Sub for L
(W + 9)*W = 162
W^2 + 9W - 162 = 0
Now, find a pair of factors of 162 that differ by 9 to factor.
You have to go the long way if L & W are not integers.
