conversations.value: Find a solution for this math problem: James wants to hang crepe-paper streamers from his backyard fence for his birthday party. His backyard fence is a rectangle that measures 20 feet on the long side and 15 feet on the short side. How many feet of crepe paper does James need to buy?

conversations.value: First figure out how much crepe paper James needs for the long sides. Since there are two long sides, multiple the side's length by 2: 20 feet * 2 = 40 feet
  Now do the same multiplication to find out how much crepe paper James needs for the short sides: 15 feet * 2 = 30 feet
  Now add the amounts for the short and long sides together to find the total amount of crepe paper needed: 40 feet + 30 feet = 70 feet
