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
---------
