    The area of a square floor on a scale drawing is 81 square centimeters, and the scale drawing is 1 centimeter:2 ft.
    so the original area is
    A = 81 sq cm ( 2 ft / 1 cm)^2a = 324 sq ft
    so the ratio of the ratio the area in the drawing to the actual area is:
    r = 81 sq cm / 324 sq ftr = 1 sq cm / 4 sq ft1 sq cm : 4 sq ft
