108.1 cm = 1 m 8 cm 1 mm

Answer 2

Given,

Length and width of the surface of Apu's desk are $62.5cm$ and $45.6cm$

We have to find the perimeter of the desk.

So, we have to use the formula of perimeter of a rectangle.

Formula,

Perimeter of a rectangle $= 2(l+b)$

Here, $l=62.5cm$ and $b=w=45.6cm$

Substitute the above values in perimeter formula,

Perimeter $= 2(62.5+45.6)$

$=2(108.1)$

$=216.2$$cm$

$216.2cm$ in $m$

$1m =100cm$

$1cm = \frac{1}{100}m$

So,

$216.2cm = 216.2\times\frac{1}{100} m$

$=2.162m$

Therefore, the perimeter of the table is $216.2cm$ or $2.162m$.
