Final answer:
In this case, the population density would be 24 residents per square mile.
Step-by-step explanation:
The best way to represent the relationship between the population of a city and its area is through population density. Population density is the number of people per unit of area.
In this case, we can calculate the population density of the city by dividing the population by the area.
So, for this city with an area of 550 square miles and a population of 13,200 residents, the population density would be: 13,200 / 550
= 24 residents per square mile.
