Answers
Given - Measurement of cloth
Find - Measurement in centimetres
Solution - He bought ( B ) 2750 centimetres of cloth.
As per the fact, 1 metre is equal to 100 centimetres.
The amount of cloth John has = 27.5 metres or 275/10 metres.
Comparing the given information, we get -
1 metre = 100 centimetres
So, the equivalent of 275/10 metres = 100*275/10
Performing multiplication and division -
Equivalent in centimetres = 2750 centimetres.
Thus, John bought ( B ) 2750 centimetres of cloth.
John bought 2750 cm of cloth.

-----------------------------------------------------------------------------------------------
Let's solve the given problem:
The length of the cloth bought by John = 27.5 m
Here we are asked to give the length of the cloth bought by John in centimeters, so we will use the above-mentioned conversion rate to convert 27.5 meters into centimeters.
Therefore,
The length of the cloth John bought in centimeters is,
= (27.5 meter) × (100 centimeter per meter)
= 27.5 × 100 centimeter
= 2750 centimeter
Thus, John bought 2750 cm of cloth.
