$225 c m$ $225 cm$

Explanation:

Converting the units in the metric system is really easy as it simply involves multiplying or dividing by powers of $10$ $10$ .
In practice this means move the decimal point to the right or left.

If you convert to a smaller unit, the number gets bigger. (multiply)
If you convert to a bigger unit, the number gets smaller. (divide)

$2 \frac{1}{4}$ $2 1/4$ m means the same as $2.25 m$ $2.25m$

$1$ $1$ metre = $100$ $100$ centimetre.

$2.25 m = 2.25 \times 100 = 225 c m$ $2.25m = 2.25xx100 = 225cm$

225 cm.

Explanation:

$2 \frac{1}{4} m = 2.25 m$ $2 1/4m=2.25m$
$1 m$ $1m$ → $100 c m$ $100cm$
$2.25 m$ $2.25m$ → $2.25 \times 100 = 225 c m$ $2.25×100=225cm$

$225$ $225$ cm

Explanation:

$2 \frac{1}{4}$ $2 1/4$ is nothing other than $2 + \frac{1}{4}$ $2+1/4$

By Taking LCM,

$\frac{2 (4) + 1}{4} = \frac{8 + 1}{4} = \frac{9}{4}$ $(2(4)+1)/4=(8+1)/4=9/4$

$\frac{9}{4}$ $9/4$ is $2.25$ $2.25$ .

1m = 100 cm

then $2.25$ $2.25$ m is ,

$2.25 \cdot 100 = 225$ $2.25 * 100=225$

$h e n c e$ $hence$ ,
$2.25 m$ $2.25m$ is $225 c m$ $225cm$ .
