Measurement

Measurement means determining the size, length, distance, height etc. of objects, place etc. The kilometer, metre, centimeter, inches and foot are the units of distance and length. While kilometer and metre are used for long and average distances, and length, centimeter, inches and foot are used to measure short distances.

 

What is Length and Breadth?

Length is the longer dimension of an object, while breadth is the dimension from side to side.

Let's see the picture given below:

     

 

Look at the following:

 

1 kilometre = 1000 metres.

1 metre = 100 centimetres.

 

Therefore,

 

2 metre = two 100 centimetres

3 metres = three 100 centimetres and the process goes on.

 

Again,

 

1 foot = 12 inches.

 

Therefore,

 

2 foot= two 12 inches = 24 inches.

3 foot = three 12 inches = 36 inches.

 

Points to remember,

Short forms,

Kilometre = km. Metre = m, Centimetre = cm

 

  • Example:

How many kilometres are there in one 1000 metres?

(a) 4                                          (b) 1

(c) 3                                          (d) 5

(e) None of these

Answer (b)

 

Explanation: (b) is correct because 1 km = one  1000 metres.

 

Note

km > m > cm

Foot> Inches>Cm
