Let represent the width. Then represents the length. The perimeter is two times the length plus two times the width, so:

The length of a rectangle is 3 yards more than twice it's width. The perimeter of the rectangle is 36 yards. What are the width and length of the rectangle?
-----------------------
Let the width be "x".
Then the length = "2x+3".
-------------------------
Perimeter = 2(length + width)
36 = 2(2x+3 + x)
18 = 3x+3
3x = 15
x = 5 yds (width)
---
2x+3 = 2*5+3 = 13 yds (length)
