Hint:
We are given a table with columns denoting different units of length. There are four rows, with some value in certain column. We are just asked the question related to third row. We have to write the quantity given in third row in centimetre. We don’t have to pay attention to other rows.
The correct answer is: 55000
The quantity given in third row is 55 dekameter.
We are asked the above quantity in centimeters.
To convert the above quantity in centimeters, we should know the relation between them.
1 dekameter = 1000 centimeter
So, to convert 55 dekameter into centimeter we will multiply the value by 1000
We get
55 decameter = 55 × 1000
= 55000 centimeter
So, the value given in the third row in centimeter is 55000.
For such questions, we should know about the conversion of different units.
