You can
put this solution on YOUR website!Well, you have started out correctly but you cannot find both the length and the width without more information.
Why is that?, because you can get the area of 80 square units in many ways:
A..=.LXW
---------
80 = 1X80
80 = 2X40
80 = 4X20
80 = 5X16
80 = 8X10
Do see the pattern here?
You need to know either the perimeter of the rug or you must have the length or the width provided.
