Question

How many square mega meters are in 9,000,000 square kilometers?

Answer 1

9 square megameters

Explanation:

Given:

`\begin{gathered} 1.0*10^6\text{ square kilometers}=1\text{ square megameter} \\ \implies1\text{ square kilometers}=(1)/(1.0*10^6)\text{ square megameter} \end{gathered}`

We want to find out how many square megameters are in 9,000,000 square kilometers.

Multiply both sides of the equation by 9,000,000.

`\begin{gathered} 1*9,000,000\text{ square km}=(9,000,000)/(1.0*10^6)\text{ square megameter} \\ \implies9,000,000\text{ square km}=9\text{ square megameter} \end{gathered}`

There are 9 square megameters in 9,000,000 square kilometers.
