in an investigation of population density in Africa, it was found that the density was 15 people/km2. How many people would you expect to find in an area of 1500 by 1.4km?

Answers

By taking the product between density and area, we conclude that there are 31,500 people in that area.

How many people would you expect to find in an area of 1500km by 1.4km?

Here we know that the density of people is:

D = 15 people/km^2

Then we need to find the area of the given region, which is just the product between the two dimensions.

Then the area is:

A = (1.4km)*(1500km) = 2,100km^2

The number of people in that area will be given by the product between the density and the area, then the number of people there will be:

N = D*A = (15 people/km^2)*(2,100km^2) = 31,500 people.
