The length of a river is '$1043\mathrm{Km}$'. Its length in meters is_

Answer 1

Since, $1\mathrm{kilometre}\left(\mathrm{km}\right)=1000\mathrm{metres}\left(\mathrm{m}\right)$

$\therefore 1043\mathrm{Km}=1043\times 1000\mathrm{m}$

$=1043000\mathrm{m}$

Therefore, the value in the blank is $1043000$
