Answer:

100 resident/km

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

A=L\cdot W = 5 \cdot 4 = 20 km^2A=L⋅W=5⋅4=20km

Now we can find the population density by using

d=\frac{N}{A}d=

where N is the number of residents, and A is the area.

Substituting N = 2000, we find:

d=\frac{2000}{20}=100 res./km^2d=

2000

=100res./km

so, 100 residents per kilometer squared
