<PRE><B>Question 520980</B>
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</PRE>
