Christopher is building a 1: 150 colon, 150 scale model of a railroad building. his model has a rectangular base that is 1.5 wide and 2 feet long. what is the area of the base of the actual railroad building in square feet?

     The model has a rectangular base; W(model) = 1.5 ft , L(model) = 2 ft.
     If the scale is 1 : 150, then the length and the width of the actual railroad building are 150 times larger.
       W = 1.5 * 150 = 225 ft
       L = 2 * 150 = 300 ft.
       Area: A = L * W = 300 * 225 = 67,500 ft²
       the area of the base of the actual railroad building is 67,500 ft².
