Answer 1

Answer:

42300000

Step-by-step explanation:

Use known fact

$1\ km=1000\ m$

Consider 1 square kilometer:

$1\ km^2=1\ km\times 1\ km=1000\ m\times 1000\ m=1000000\ m^2$

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

$42.3\ km^2=42.3\times 1000000\ m^2=42300000\ m^2$
