Billy’s dogs wouldn’t stay in his yard, so his parents decided to build a rectangular fence to keep them in. The fence was 15 2/3 feet long and 20 1/2 feet wide. What is the perimeter of the fence?
Since the perimeter is when you add up for sides. First, you multiply 15 2/3 x 2 to get 31 1/3. You do the same thing for the second number 20 1/2 times 2 to get 40. Next, you add 31 1/3 times 41 to get 1284 2/3.
