Question

Which region has a population density less than 60 animals per square mile

Answer 1

Explanation

We will have to find the population density of each of the regions

To get the population density, we will have to divide the population of each region and then divide by the area of the of each region

For part A

$Area=\frac{1}{2}\times40\times35=700mi^2$

The population density of region A is

$\frac{42500}{700}=60.71\text{ animals per square miles}$

For region B

The area of region B is

$\frac{1}{2}\times50\times38=950mi^2$

The population density of region B is

$\frac{60800}{950}=64\text{ animals per square miles}$

For region C

$area=\frac{1}{2}\times42\times49=1029mi^2$

The population density of region C

$\frac{57300}{1029}=55\text{ animals per square mile}$

Thus, we can observe that Region C has a population density lower than 60 animals per square miles

Thus, option C is correct
