Answer Details
To calculate the population density of a country, you need to divide the total population of the country by its total area.
In this case, the population of the country is 20,000,000 and its size is 1,000,000 km2. So, to calculate the population density, you can divide 20,000,000 by 1,000,000.
20,000,000 / 1,000,000 = 20
Therefore, the population density of this country is 20 persons/km2.
