Nancy wants to make a square garden with an area of 225 square feet. How long should she make each side of the garden?

56.25 feet

Step-by-step explanation:

Since area is length * width, you know you have to multiply. Since it says that her garden is a square, that is how you know you have 4 sides. And 225 (the area) divided by 4 is 56.25. So each side should be 56.25 feet.
