3. Suppose you have a rectangular garden that is 10 ft by 40 ft. The garden has become too much to manage, so you plan to install a square-shaped fountain in the middle. Square-shaped fountains come in all sizes, so you decide to buy one that will leave only 100 ft of garden to maintain, which is all you have the energy for. What should the side length of the fountain be? After finding your two "answers", explain why neither actually makes sense in this problem! WISE, VIZ
