Question: An octopus lives in an underwater garden that is shaped like a rectangle. The fence around the garden is 7 feet on the long sides and 5 feet on the short sides. Draw a picture of the garden on graph paper. How many 1-foot squares are in the octopus's garden, and how many feet of fence go around it?
Answer: 35 square feet in area, 24 feet in perimeter
Solution: If we draw a picture of the garden broken into square feet, it’ll look like this:
