Question

A square region has a population of about 200,000 people and a population density of about 1650 people per square kilometer. Find the side length of the square region to the nearest kilometer.

The side length of the square region is about ___ kilometers.​

Answer 1

The side length of the square region is about 181,166 kilometres.

Explanation:

population density = no. of people / area of region

given

population = 200,000

population density = 1650 people per square kilometers

1650 = 200,000/area of region

=> area of region = 1650*200,000 = 330,000,000

given that region is square in shape

area of square = side^2

side^2 = 330,000,000

side =
`√( 330,000,000) = 181165,90`

The side length of the square region is about 181,166 kilometres.
