The population density is approximately 4 people per square mile 
Calculating Population Density 
From the question, we are to determine the population density 
Population density is given by the formula, 
[tex]Population\ density = \frac{Number\ of\ people}{Land\ area}[/tex]
Number of people in the town = 12620 people 
Now, we will determine the land area of the town 
From the given shape,
Land area of the town = (60 × 65) - (25 ×40)
Land area of the town = 3900 - 1000
Land area of the town = 2900 square mile 
∴ Population density = [tex]\frac{12620}{2900}[/tex]
Population density = 4.3517 
Population density ≅ 4 people per square mile
Hence, the population density is approximately 4 people per square mile
