Question

. The land area of Charlotte, NC is approximately 3 x 102 square miles.

Answer 1

Answer:

Option A

Step-by-step explanation:

Land area of Charlotte, NC = $3\times 10^2$ square miles

Scale to be used,

1 square miles = $6.4\times 10^2$ square acres

By this scale,

$3\times 10^2$ square miles = $(6.4\times 10^2)\times(3.2\times 10^2)$ square acres

                                  = $(6.4\times 3)\times 10^{2+2}$

                                  = $19.2\times 10^4$ square acres

                                  = $1.92\times 10^5$ square acres

Therefore, Option A will be the correct option.
