Question

A room is 12 feet long and 10.5 feet wide. A scale model of the room is 3.5 feet wide. What is the area of the scale model?

2 Answer

  • scale of the model = 3.5 / 10.5 = 1/3
    so the length of the model = 1/3  * 12 = 5 feet

    Area of the scale model = 4 * 3.5 = 14 sq ft
  • if 3.5 is one third of 10.5 than one third of 12 must be four. 3.5 times 4 is
    14
