To find the land area of the town, we can use the formula for population density:
\[ \text{Population Density} = \frac{\text{Total Population}}{\text{Land Area}} \]
We can rearrange this formula to solve for land area:
\[ \text{Land Area} = \frac{\text{Total Population}}{\text{Population Density}} \]
Given that the total population is 210,756 and the population density is 52 residents per square mile, we can plug in the values:
\[ \text{Land Area} = \frac{210,756}{52} \]
Now, we will do the division:
\[ \text{Land Area} = 4,045.307692307692 \approx 4,045.31 \text{ square miles} \]
Thus, the town’s land area is approximately 4,045.31 square miles.
