Word Problems on Measuring Length

We will discuss here how to solve the word problems on measuring length (i.e. addition and subtraction).

Addition and subtraction in meters and centimeters is done in the similar way as in the case of ordinary numbers.


Note:

(i) When we add meters and meters the sum is in meters and when we add centimeters and centimeters the sum is in centimeters. Here centimeters are written as two digit number.

(ii) When we subtract meters from meters the difference is in meters and when we subtract centimeters from centimeters the difference is in centimeters. Here centimeters are written as two digit number.


Solved word problems on measuring length:


1. Sita is 1 m 30 cm tall and her sister Rita is 1m 60 cm tall. Who is taller and by how much?

Solution:

Height of Rita = 1 m 50 cm

Height of Sita = 1 m 30 cm


               m        cm

                1        50 

             -  1        30 

                           20


Rita is taller by 1 m 50 cm - 1 m 30 cm = 20 cm


2. Maria purchased 24 m 25 cm rope and Nancy purchased 17 m 15 cm rope. What is the total length of ropes both of them purchased?

Solution:

Length of ropes purchased by Maria = 24 m 25 cm

Length of ropes purchased by Nancy = 17 m 15 cm

Total length of ropes purchased by them = 24 m 25 cm + 17 m 15 cm

                                                           = 41 m 40 cm

 

3. Subtract 20 m 15 cm from 36 m 95 cm.

Solution:

First arrange meters and centimeters in columns.

Then subtract 15 cm from 95 cm.

95 cm - 15 cm = 80 cm

Write it in centimeter column.

Then subtract 20 m from 36 m.

36 m - 20 m = 16 m

Write this in metre column.

The answer is 16 m 80 cm.

                 m           cm

                36           95

       -        20           15

                16            80


4. Mary is 1 m 15 cm tall. Her friend Larry is 1 m 30 cm tall. Who is taller and by how much?

Solution:

The height of Mary = 1 m 15 cm

The height of Larry = 1 m 30 cm

Difference between their height

           = 1 m 30 cm - 1 m 15 cm

           = 15 cm

Larry is taller by 15 cm.


                m            cm

                1             30

       -        1             15

                 0             15


5. Aaron bought 9 m 75 cm of cloth. He used 2 m 30 cm from it. How much cloth is left?

Solution:

Total length of cloth Aaron bought = 9 m 75 cm.

Length of cloth he used = 2 m 30 cm.

Therefore, the length of cloth left = 9 m 75 cm - 2 m 30 cm

                                              = 7 m 45 cm
