If a map has a scale of 4cm to 12km what does 20cm represent?

To find out what 20cm represents on the map with a scale of 4cm to 12km, you first need to determine the scale factor. In this case, the scale factor is 12km divided by 4cm, which equals 3km per cm. Then, you can multiply the scale factor by 20cm to find out what it represents on the map. 20cm multiplied by 3km per cm equals 60km. Therefore, 20cm on the map represents 60 kilometers in actual distance.
