Answer

Explanation:

Step1: Convert land - area to standard units

Since 1 million = 1000000, 8.5 million square kilometers = 8.5×1000000 = 8500000 square kilometers.

Step2: Use the population - density formula

The population - density formula is Population density=$\frac{Population}{Area}$. Rearranging for population gives Population = Population density×Area. The population density is 23 people per square kilometer and the area is 8500000 square kilometers. So, Population = 23×8500000. 23×8500000=(20 + 3)×8500000=20×8500000+3×8500000=170000000+25500000 = 195500000 people.

Answer:

195,500,000 people
