Population density can be found by dividing the number of people by the area of the land.
number of people / land area
The population is 20,510 people and the area is 86.8 square miles.
20,510 people / 86.8 square miles
Divide 20,510 by 86.8
236.290323 people /square mile
Round to the nearest tenth. The 9 in the hundredth place tell us to round the 2 to a 3 in the tenth place.
236.3 people/ square mile
There are 236.3 people per square mile and B is correct.
