How do I solve the following?

Sharon needs to create a fence for her new puppy. She purchased 40 feet of fencing to enclose three sides of a fence. What dimensions will create the greatest area for her puppy to play? (I'm confused by the three sides. I know I need to create a polynomial and find the maximum using the formulas for area and perimeter but I don't know how to do this.)

If the three sides is accurate, then the fenced area would be a triangle. A triangle with the greatest area is equilateral. 40/3 = 13.333 feet on each side. This would provide an area of `~~` 77 square feet.

If it is supposed to be four sides, then the fenced area would be a quadrilateral. A quadrilateral with the greatest area is square. 40/4 = 10 feet on each side. This would provide an area of 100 square feet.
