The ceiling of Katie's living room is a square that is 15 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 20 ft of crepe paper. What is the minimum number of rolls she should buy? ( Show Your Work). Will Mark Brainliest if answered correctly and please do not reshare another students answer from brainly or any other websites to answer my question or you'll be reported. Thank you.
