Question

In 2010, the population of Houston, Texas, was 2,099,451 and the population density was 3,501 people per square mile. What was Houston's land area in 2010? Enter your answer as a decimal in the box. Round your answer to the nearest tenth. mi²

Answer 1

I would say 600 sq mi ie divide the population 2099451 by the population density 3501 people per sq mi to get 599.6 sq mi or rounded off to the nearest 1\10th is 600 sq mi.

Answer 2

The population density can be calculated as the ratio:
population density=number of people/land area
From this equation we can write the following equation in order to calculate the land area: land area=number of people/ population density
In our case, number of people in Houston=2099451
population density in Houston=3501

land area=599.67 mi2
