Given : Map is drawn using a scale of 1 cm to 8 km.
To Find : the R.F. of the map
Find in cm, the distance on the map between two places which are 72 km apart
Find in cm², the area on the map of a forest which has an area of 496 km²2
Solution:
RF = Representative Factor
RF = Dimension of Drawing / Dimension of Object
= 1 cm / 8 km
1km = 1000 m
1 m = 100 cm
1 km = 100000 cm
8 km = 800000 cm
= 1 cm /800000 cm
RF = 1 : 800000
8km = 1 cm
=> 72 km = 9 cm
the distance on the map between two places which are 72 km apart is 9 cm
1 cm = 8 km
1 cm² = 64 km²
64 km² = 1 cm²
=> 496 km² = 496/64 = 7.75 cm²
the area on the map of a forest which has an area of 496 km² is 7.75 cm²
