Question

If $1{\mathrm{m}}^2=\mathrm{x}{\mathrm{mm}}^2$, then the value of $\mathrm{x}$ is

• A. $1000$
• B. $10000$
• C. $100000$
• D. $1000000$

Answer 1

The correct option is D

$1000000$

Explanation for the correct answer:

We know that,

$1\mathrm{m}=1000\mathrm{mm}$

Therefore, $1m^2=1m\times 1m$

$\Rightarrow$ $1{\mathrm{m}}^2=1000\mathrm{mm}\times 1000\mathrm{mm}$

$\Rightarrow$ $1{\mathrm{m}}^2=1000000{\mathrm{mm}}^2$

Hence, the value of $\mathrm{x}$ is $1000000$, so, option $\left(\mathrm{D}\right)$ is the correct answer.
