Population density is the number of people per unit of area. The population density of a certain region is 45 people per square kilometer. If the region covers 33 square​ kilometers, what is the population of the​ region? The population of the region is people.

45 ppl / km2   *  33 km2  = 1485 ppl

If we know that there are 45 people per square kilometer and there are 33 square kilometers we can make this equation:

45 * 33 = y

(the * is another way write multiplication) 
 

All we have to do is multiply the numbers!

45 x 33 = 1,485

I hope this helps! :D
