Atownship is in the shape of a rectangle that is 5 km long and 4 km wide. there are 2000 residents in the township. what is the population density of the township?

100 residents/

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

Now we can find the population density by using

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

Substituting N = 2000, we find:

so, 100 residents per kilometer squared.

the discriminant is 64 + 4*1*12 = 112

this is prime.
