Now, in this question we have to find out how much a measurement of 9 cm and 5 mm is going to measure entirely in mm.

So let us first apply the length conversion chart :

We know that

$1cm = 10mm$

So by direct unitary method, if $1cm = 10mm$,

then $9cm$ will be $1cm = 10mm$multiplied with 9. That is,

$

9 \times 1cm = 9 \times 10mm \\

\Rightarrow 9cm = 90mm \\

$

Now, out of 9 cm and 5mm we have already converted 9cm to mm and got 90mm. Now the remaining 5 mm is already in mm so it does not need any further conversion.

Hence, it will suffice to simply add it to the 90mm.

That is 9 cm 5mm can be written as:

$9cm + 5mm$

So, putting $9cm = 90mm$ and $5mm = 5mm$ we will get

$

9cm5mm \\

= 90mm + 5mm \\

= 95mm \\

$

That is 9 cm 5 mm is = ….95….. mm.

$

9m + 5cm \\

= 900cm + 5cm \\

= 905cm \\

Units play a very important role in our day to day lives. While the smaller units like millimeters are used to measure the smallest of lengths like-thickness of a coin or a page, the bigger units like kilometer are used to calculate distances between two cities while meter is used to measure cloth or distance between two people standing in a room.
