Sos me! the area of china is 5,956,960 sqkm. in july china's population was estimated at a,313,973,713 people. what is the population density iof china in people per sq kilometer
and explain how you got it

Here's a tool for your math toolbox:

     Wherever you see the word "per", it wants division.
     You should begin with a fraction.

       "People per square kilometer"
means
       (number of people) / (number of square kilometers) .

The problem just gave you both of those numbers.  So it's time to
polish up your pencil or your calculator and get to work dividing.

Notice that you made a mistake copying the estimated population
of China, and then, even worse than that, you didn't proofread your
question and correct the copying mistake.

            (Population) / (area) =

            (1,313,973,713 people) / (5,956,960 sq km) =

             220.6 people per square km.

Geometric pattern of 2 i’m guessing. not really sure about what you’re asking but i hope this !
