The height of a person is $ 1.45 \mathrm{~m} $. Express it into $ \mathrm{c} \mathrm{m} $ and $ \mathrm{mm} $.
Given:
Height of the person = $1.45\ m$
To find: Express the height into $cm$ from $m$.
Solution:
We know that:
$1m=100cm$
It means when the length value in meters $(m)$ is multiplied by
$100$, then it gets converted into centimeters $(cm)$
Therefore,
$1.45m=1.45\times100\ cm$
$1.45m=\frac {145}{100}\times100\ cm$
$1.45m=145\ cm$
Thus, in $cm$, $1.45m$ is equal to $145cm$.
