You can put this solution on YOUR website! A rectangular family room has an area of 160 sq ft. THe length of the room is 6 ft greater than its width, Find the width and length of the room.
--------------------------
Let width be "x"
Then length is "x+6"
-----
Equation to solve for "x"::
x(x+6) = 160
x^2 + 6x - 160 = 0
------
(x+16)(x-10) = 0
---
x = 10 ft (width)
x+6 = 16 ft (length)
