Tracy has 40 feet of material to make the perimeter of a rectangle sandbox for her little brother what rectangle with whole number side length would give the sandbox with the greatest area?
I personally think this: length = 10 feet width = 10 feet
I think the length should be 10 and bredth be 10. This will result into greatest area with the same perimeter. Area = 10 * 10 = 100 Perimter = 4 * 10 = 40
