1. ## quadratic area word problem

A rectangle has a length 2 meters less than twice its width. When 5 meters is added to the width, the result is a square with an area of 144 square meters. Find the dimensions of the original rectangle.

(w+5)*(2w-2)=144?

2. original width : $w$
original length : $2w-2$
New width: $w+5$
New area = 144

So $(w+5)(2w-2)=144$

[Note that the length is not changed]

So $(w+5)(w-2)=144$
Wouldnt it be (w+5)(2w-2)=144?

4. LOL, my bad, i didn't see the "twice"

(w+5)(2w-2)=144 is correct
