Delilah and Spence wanted a deck built onto their house. They wanted the deck to be a five sided shape with each side being 12 feet long. What is the perimeter of the deck?
Each side is 12 feet long and there are 5 sides. So to find the perimeter you add 12 together 5 times. 12+12+12+12+12 or multiply 12*5. Both equal 60 feet.
