Question

One square megameter is equal to 1.0×106 square kilometers. How many square megameters are in 9,000,000 square kilometers?

Answer 1

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 $1.0\times 10^{6}$ square kilometers.

So, $1.0\times 10^{6}\textrm{ }km^{2}=1\textrm{ Mm}$

∴ $1.0\textrm{ }km^{2}=\frac{1}{1.0\times 10^{6}}\textrm{ Mm}$

So, $9000000\textrm{ }km^{2}=\frac{1}{1.0\times 10^{6}}\times 9000000=\frac{9000000}{1000000}=9\textrm{ Mm}$

Therefore, there are 9 square mega-meters in 9,000,000 square kilometers.
