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

9,000,000 square kilometers is equal to 9 square mega-meters.

Explanation:

Given:

One square mega-meter is equal to
`1.0* 10^(6)` square kilometers.

So,
`1.0* 10^(6)\textrm{ }km^(2)=1\textrm{ Mm}`

∴
`1.0\textrm{ }km^(2)=(1)/(1.0* 10^(6))\textrm{ Mm}`

So,
`9000000\textrm{ }km^(2)=(1)/(1.0* 10^(6))* 9000000=(9000000)/(1000000)=9\textrm{ Mm}`

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