THE MAP.................

Answer 2

First find out the scale of the map.

For example, if a topographic map has a scale of 1:50 000. ...

If the scale of the map in RF is 1:50 000, then each cm represents 0.5km.

Length: 2cm x 0.5km = 1.0 km.

Width: 2cm X 0.5 km = 1.0km.

Area of One Grid Square = 1.0km x 1.0km = 1.0 sq. km.
