Question

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?

Answer 1

I personally think this:

length = 10 feet

width = 10 feet

Answer 2

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
