Answer:
[tex]133.2\text{ Miles}^2[/tex]
Step-by-step explanation:
We have been given that in 2010, the population of Atlanta, Georgia was 419,979 and the population density was 3153 people per mi².
Since we know that [tex]\text{Population density}=\frac{\text{Number of people}}{\text{Land area}}[/tex], so upon substituting our given values in above formula we will get,
[tex]\frac{\text{3153 people}}{\text{Miles}^2}=\frac{419,979\text{ people}}{\text{Land area}}[/tex]
[tex]\text{Land area}=\frac{419,979\text{ people}}{\frac{\text{3153 people}}{\text{Miles}^2}}[/tex]
[tex]\text{Land area}=\frac{419,979\text{ people}}{\text{3153 people}}\times \text{Miles}^2[/tex]
[tex]\text{Land area}=133.1998097\text{ Miles}^2\approx 133.2\text{ Miles}^2[/tex]
Therefore, the Atlanta's land area was 133.2 square miles.
