Answer:
9,000,000 square kilometers is equal to 9 square mega-meters.
Step-by-step explanation:
Given:
One square mega-meter is equal to [tex]1.0\times 10^{6}[/tex] square kilometers.
So, [tex]1.0\times 10^{6}\textrm{ }km^{2}=1\textrm{ Mm}[/tex]
∴ [tex]1.0\textrm{ }km^{2}=\frac{1}{1.0\times 10^{6}}\textrm{ Mm}[/tex]
So, [tex]9000000\textrm{ }km^{2}=\frac{1}{1.0\times 10^{6}}\times 9000000=\frac{9000000}{1000000}=9\textrm{ Mm}[/tex]
Therefore, there are 9 square mega-meters in 9,000,000 square kilometers.
