Question

$1{\mathrm{km}}^2={\mathrm{\_\_\_\_\_\_m}}^2$.Fill in the blanks.

Answer 1

Representation of $\mathrm{km}$ in $\mathrm{meter}$.

Since,

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

So,

$$\begin{gathered} 1{\mathrm{km}}^2=1000\times 1000 \\ =1000000{\mathrm{m}}^2 \end{gathered}$$

Hence, $1{\mathrm{km}}^2=1000000{\mathrm{m}}^2$.
