Solution

Step 1: Converting the number into same unit
A tailor uses $2 m 20 c m$ of cloth for making a shirt
We know that $1 m = 100 c m$
Thus $2 m = 200 c m$
So, $2 m 20 c m = 200 + 20 = 220 c m$

Step 2: Finding the length of cloth required
According to the question $18$ such shirts are to be made
That is $220 c m \times 18 = 3960 c m$
$3960 c m = 3900 c m + 60 c m$
$= 39 m 60 c m$
Hence, the length of cloth required for making $18$ shirts is $39 m 60 c m$ .
