You can put this solution on YOUR website! The length of a rectangle is 2 ft more than twice the width. The area of the rectangle is 84ft2. Find the length and width of the rectangle.
-------------------
Let the width be "x" ft.
Then the length is "2x+2" ft.
--------------------------------------
Area = WL
84 = x(2x+2)
42 = x(x+1)
x^2 + x - 42 = 0
(x+7)(x-6) = 0
----
x = 6 ft (width)
2x+2 = 12+2 = 14 ft (length)
