Answer:
The side length of the square region is about 181,166 kilometres.
Step-by-step 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 = [tex]\sqrt{ 330,000,000} = 181165,90[/tex]
The side length of the square region is about 181,166 kilometres.
