The population of California = [tex]2.52 \times 10^7[/tex] people.
Land area of California = [tex]4.05 \times 10^5km^2[/tex].
We have to determine the average number of people per square kilometer.
Average number of people per square kilometer =
Land area of California [tex]\div[/tex] Population of California
= [tex]4.05 \times 10^5 \div 2.52 \times 10^7[/tex]
= [tex]1.6 \times 10^{-2}[/tex]
Therefore, the average number of people per square kilometer is [tex]1.6 \times 10^{-2}[/tex].
