1 : 20 000 is the same as
1 cm : 20 000 cm or
1 cm : 0.2 km
Area scale is (1 cm)2 : (0.2 km)2 = 1 cm2 : 0.04 km2
Map is 18 cm2
So the actual area is 18 cm2 x 0.04 km2 / 1 cm2 = 0.72 km2
1 cm : 20 000 cm or
1 cm : 0.2 km
Area scale is (1 cm)2 : (0.2 km)2 = 1 cm2 : 0.04 km2
Map is 18 cm2
So the actual area is 18 cm2 x 0.04 km2 / 1 cm2 = 0.72 km2
