If a rectangle with perimeter has a length that is units longer (or shorter if ) than times the width, ,

Then knowing that the Perimeter is given by:

,

make the substitution:



Then solve for







For your problem: , , and . Do the arithmetic.

The lenght of a rectangular pool is 5 feet less than three times the width. If the perimeter in 198 feet, find the length and width of the pool.
**
let W=width
3W-5=length
perimeter=2W+2L=198=2W+2(3W-5)=2W+6W-10
198=8W-10
8W=208
W=26
L=3W-5=73
ans:
Width=26 ft
Length=73 ft
