Answers
As per the data given in the question,
In the above question, it is given that,
Given that the length of the book rack is21.5m.
Here we have to express in centimetre and millimetres.
We have to use the formula of conversion from m to cm and millimetres.
Thus, the conversion of meters in centimetres and millimetres.
1meter =100centimeter
1Centimeter=10millimeters
Therefore,21.5m=2150centimeters
In millimetes 21500millimeters.
Hence 21.5m in terms of centimetres is 2150cm and in terms of millimetres 21500.
Here it is given that the length of a book rack is 21.5 m
We have to convert this length into centimeter and millimeter
Now, to convert meter into centimeter the conversion factor is 100
This means that we have to multiply the value by 100
So, 21.5 m = 21.5 × 100 cm
= 2150 cm
to convert meter into millimeter the conversion factor is 1000
This means that we have to multiply the value by 1000
21.5 m = 21.5 × 1000 mm
= 21500 mm
Hence, 21.5 m is equal to 2150 cm and 21500 mm
