Q : 4    Nasreen bought 3 m 20 cm cloth for her shirt and 2 m 5 cm cloth for her trouser. Find the total length of cloth bought by her. 

Answers (1)

Length of cloth for shirt =  3 m 20 cm                                    

Length of cloth for trouser =  2 m 5 cm
                                       

As we know.

For adding two numbers their unit must be the same.

So making length in meter:

            3m+20cm=3\:m+\frac{20}{100}m

                                      =3\:m+0.2m

                                      =3.2m

and 

                   2m+5cm=2\:m+\frac{5}{100}m

                                          =2\:m+0.05m

                                          =2.05m

Now,

     Total Length of the cloth = 3.2 m + 2.05 m 

                                            =  5.25 m

Hence Nasreen bought clothe with a length of 5.25 m.
