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)
