The distance between cities a and b on the map is 2 cm, map scale is 1: 7500000. find the distance between cities a and b in the area.

In this task, you need to find the real distance between two cities. At the same time, their distance is indicated in a reduced form on the map, as well as the scale of this map.
The scale of the map allows you to determine how many times all the details on the map have been reduced. That is, the distance between cities has been reduced as many times as the map scale.
Therefore, to find out the real distance between cities, you need to multiply the distance on the map by the scale:
2 cm * 7500000 = 15,000,000.
Answer: 15,000,000 cm.
