 Question 249634: The length of a rectangle is 1cm more than twice the width. If the area is 78cm (squared). Find the dimensions. I came up with this so far? L=2w +1 2w+1(w)=78 2w(squared)+w=78 then 2w(squared)+w - 78 = 0 I factored that as (2w + 13) and (2w - 6) = 0 But then I would be getting W = -13/2 and W = 6 Am I on the right track? I'm supposed to be finding the dimensions of the rectangle. Thanks Click here to see answer by richwmiller(9132)
