you do for the length x and width x-12

then do x+x+x-12+x-12=108 and add all those up subtract 24 from both sides divide the x's from both sides and you get the answer

Let the length = x. Then the width should be x-12. To find the perimeter of a rectangle 2(l*w)=Perimeter. So you have a algebraic equation when you sub in your numbers. 2(x*(x-12))=108 Do you understand how I did that?

Whoops! Sorry. That formula should be 2(l+w)=Perimeter. Thanks igloo :)
