If the total population of a country is 25,000,000 and her total land area is 100,000 square kilometres,what is her population density?

Answer Details

Population density is the number of people living in a certain area, typically expressed as the number of individuals per unit of land area. To calculate population density, we need to divide the total population of a country by its land area. In this case, the population density of the country can be calculated as: Population density = Total population / Land area Substituting the given values, we get: Population density = 25,000,000 / 100,000 Population density = 250 people per square kilometer Therefore, the correct answer is: 250 persons per sq. km.
