What is the area of a forest if on a map with a scale of 1: 20000 it is depicted as a rectangle with sides of 5 cm and 8 cm?

1) Scale 1: 20000 means that in 1 cm: 200 m;

2) The first side of the forest area will be equal to a = 5 * 200 = 1000 m;

3) The second side of the forest area will be equal to h = 8 * 200 = 1600 m;

4) The area of the site will be equal to S = a * b = 1000 * 1600 = 1600000 m2;

Total: S = 1,600,000 m2.
