In an area of 250 square miles, the population is found to be 5,000 persons. find the population density. a. 5,250 persons/square mile b. 20 persons/square mile c. 1,250,000 persons/square mile d. 0.05 persons/square mile( explain your answer, also i need asap! )

B.20

Step-by-step explanation:

First you need to know that in order to find population density you must divide the total amount of people in a population, by the amount of land or square miles/kilometers, but it must be squared, which in this case is perfect.

Second, you would set it up as a fraction with 5000/250

Third, you would hopefully calculate that it equals 20

Hence your answer of 20 persons/square mile.
