20,000 per sq. km.

Step-by-step explanation:

In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...

= k

20,000 per sq. km. = k

Finally, we can see that the value of k is 20,000 per sq. km.
