Answer:
Option A
Step-by-step explanation:
Land area of Charlotte, NC = [tex]3\times 10^2[/tex] square miles
Scale to be used,
1 square miles = [tex]6.4\times 10^2[/tex] square acres
By this scale,
[tex]3\times 10^2[/tex] square miles = [tex](6.4\times 10^2)\times(3.2\times 10^2)[/tex] square acres
= [tex](6.4\times 3)\times 10^{2+2}[/tex]
= [tex]19.2\times 10^4[/tex] square acres
= [tex]1.92\times 10^5[/tex] square acres
Therefore, Option A will be the correct option.
