What rectangle with whole-number side lengths would give the sandbox with the greatest area?
There is 40 feet of material
Because squares are also rectangles, you need to divide 40 feet into equal squares of a maximum size. If you divide 40 by four you will get a 10 by 10 square will be the most appropriate to give a maximum area.
11x9 or 10x10 if u count squares as rectangles!
10x10a square would give you the greatest area, so you divide 40 by 4 to find the side length.squares are rectangles.
