(1) First, determine the appropriate proportion.

12cm:6m = 12cm:600cm = 1:50

4mx (1:50) = 0.08m = 8cm

Length drawn on paper = 12cm, width = 8cm;;

(2) Calculate the ratio between the drawing area and the actual living room area.

The ratio of the area on the drawing to the actual area = 12x8cm? :6x4m? = 12x8cm? :6x4x 10000cm? = 1:2500= 1:50? ,

1m? = 10000cm?

The ratio of the area on the map to the actual area = the square (ratio)
