conversations.value: Solve the math problem: James has a room that is 13 feet by 18 feet.  He increases each dimension by 2 feet.  He then builds 3 more rooms of equal size and 1 room of twice that size.  How much area does he have?
conversations.from: assistant
conversations.value: He increases the length to 13+2=15 feet
  He increases the width to 18+2=20 feet
  So the rooms are 15*20=300 square feet
  So he has 1+3=4 rooms of this size
  So he has 4*300=1200 square feet of rooms this size
  He also has one room of size 300*2=600 square feet
  So he has 1200+600=1800 square feet of rooms
