A rectangular parking lot has length that is 7 yards less than twice its width. If the area of the land is 130 square yards, what is the dimensions of the land?
--------------------
length = 2*width - 7
--------
Area = length * width
-----------------------
Equation:
130 = (2w-7)*w
----
2w^2 - 7w - 130 = 0
Factor::
(w-10)(2w+13)
-----
Positive solution:
width = 10 yds
length = 2w-7 = 13 yds
-----------------------------
