there is no limit.
There must be some other considerations.
what is the greatest perimeter of a rectangle with an area of 39 square feet

well it said on my homework
Do the dimensions have to be in whole numbers?
Well, your homework is poorly stated.
Here is an example of what Steve is saying:
suppose the width is .1 ft
then the length = 39/.1 or 390 ft
perimeter = 2(390) + 2(.1) = 780.2 ft
check: area = .1(390) = 39
suppose the width is .001 ft
then the length is 39/.001 or 39000 ft
perimeter = 2(39000) + 2(.001) = pretty big
As you can see we can make the perimeter as large as we want to by making the width smaller and smaller, and still keep an area of 39

I had it on my homework too.
