Set up an expression for L in terms of W. E.g., you know how the length is related to the width, so use that to write an expression for length (in terms of width). Then use the formula for perimeter: P=2L + 2W with your expression that has L in terms of W, so you'll have 72={some expression involving W's} Then solve for W, substitute it back in to solve for L.

16.5 would be the width, 19.5 would be the length.

Yeah, I could have done that and saved myself a lot of typing. @cyberianhd , welcome to Open Study.

@DebbieG I'm sorry, I had no idea you couldn't say the answer. I just noticed that your explanation sounded exactly like a teachers, and, coming from a student, is most likely why most people on this website post help because the teachers explanation is over complicated.

Then feel free to give a "less complicated" explanation. I always explain the process and then wait to see what the student does with it, and what questions they have. I am always happy to elaborate or break it down, but not EVERY student NEEDS that, some just need to pointed in the right direction. However, nobody learns anything about HOW to do a problem, if they are just handed the answer. That isn't the purpose of this site. It IS to TEACH HOW to approach the problem.
