<PRE><B>Question 686489</B>
The length of a rectangle is twice the width. 
The perimeter is 36 feet. Find the length and width. 
Unknowns: 
______x_______ = width
______2x_______ = length
-------------------------------------------- 
Write and equation and solve: (Remember that perimeter is 2l + 2w.)
----
Perimeter = 2(length + width)
36 = 2(2x + x)
18 = 3x
x = 6
-------- 
Width = x = 6 feet
------
Length = 2x = 12 feet
---------
