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, because one square megameter is equal to one million square kilometers.

Answer 2

Answer: There are 9 square megameters in 9000000 square kilometers.

Step-by-step explanation:

Since we have given that

1 megameter square = 1.0×10⁶ square kilometers

So, we will use "Unitary method":

1 square kilometer = $\dfrac{1}{1.0\times 10^6}$

So, 9000000 square kilometers is given by

$\dfrac{9000000}{10^6}\\\\=\dfrac{9\times 10^6}{10^6}\\\\=9$

Hence, there are 9 square megameters in 9000000 square kilometers.
