Homework Help: math

Posted by Chad on Monday, March 1, 2010 at 9:37pm.

The length of a rectangle is 2 cm more than three times the width. Find the dimensions of this rectangle if the area is 21 cm^2.

I know the answer is 9 & 2 1/3 but I found it by trial and error. Is there an easier way to find the answer to this question? Thanks!
