Answer:
1380 people.
Step-by-step explanation:
Population density is a number of people per unit of area.
We have,
The population density of sick in a certain region = 60 people/km²
Area of the region, A = 23 km²
We need to find the population of the region.
[tex]d=\dfrac{P}{A}\\\\P=60\times 23\\\\P=1380\ \text{people}[/tex]
So, the population of the region is equal to 1380 people.
