This problem doesn't seem to make sense based on the context of the problem.

Jordan wants to fill a square flower bed with 24 perennials. The landscaper recommends that he allow 1.5 square ft per plant. What should the length of one side of the flower bed be.

Now squares have all equal sides. 24 is not a perfect square. So how are you to fill a square flower bed with 24 flowers without there being a gap somewhere. Am I nuts or is this problem not possible given the context?

The only thing I can think of is a 5x5 with the middle space empty. But then that to me doesn't fulfill the part of the problem where it says FILL the flower bed with 24 perennials. Unless it is typical of flower beds to have a gap in the middle?
