# 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.

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.
