Question

Jeremy‘s puppy has a dog pen that has an area 500 ft.². He is planning on putting a new fence around the perimeter the pen. About how much fencing will Jeremy need?

Answer 1

We are not told whether the shape of the pen is to be square or rectangular or some other shape.

If we assume the pen is to be square, then the side length is approx. √(500 ft^2), or 22.4 ft.
