Answer:
100 residents/[tex]km^2[/tex]
Step-by-step explanation:
In order to find the population density, we have to calculate the area of the township first.
We know that:
L = length = 5 km
W = width = 4 km
So the area of the township is
[tex]A=L\cdot W = 5 \cdot 4 = 20 km^2[/tex]
Now we can find the population density by using
[tex]d=\frac{N}{A}[/tex]
where N is the number of residents, and A is the area.
Substituting N = 2000, we find:
[tex]d=\frac{2000}{20}=100 res./km^2[/tex]
so, 100 residents per kilometer squared.
