the scale of a map is 1;20,000. calculate the area, in square centimeters, on the map of a forest reserve which covers 85 kilo meter rest up power 2

Answer 1

"85 kilo meter rest up power 2" ?? -- you mean 85 km^2
area grows as the scale factor squared.
20,000cm = 200m = 0.2km
So, each cm^2 represents (0.2km)^2 = 0.04 km^2

85/0.04 = ____ cm^2

or,
5cm represents 1 km
so, 25cm^2 = 1 km^2
85 * 25 = ____ cm^2
