The ceiling of Ben's living room is a square that is 18ft long on each side. To decorate for a party he plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Ben can buy rolls that each contain 25ft of crepe paper. What is the minimum number of rolls he should buy? show work

Total distance to cover = 4 * 18 + 2 * sqrt(18^2+18^2) = 123 ft


123 / 25 = 5 rolls
