conversations.value: Please show me the solution for: Mark made a chalkboard that is 3 feet wide. It is 2 times as long as it is wide. What is the area of the chalkboard?
conversations.from: assistant
conversations.value: The length of the chalkboard is 2 x the width of 3 feet = 6 feet.
  We can calculate area by multiplying the width and the length, so 3 feet x 6 feet = 18 feet.
