The area of a square floor on a scale drawing is 16 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
1 cm : 3 ft ... squaring ... 1 cm^2 = 9 ft^2
area = 16 cm^2 * 9 ft^2/cm^2 = ? ft^2
