    Answer:

    Cloth bought by Nasreen for her shirt = 3 m 20 cm = 3 m + 20 cm \[\] \[\] \[\] Cloth bought by Nasreen for her trouser = 2 m 5 cm = 2 m + 5 cm \[2\times \frac{1}{10}+6\times \frac{1}{100}=0.26\] \[1\times 1+3\times \frac{1}{10}+8\times \frac{1}{100}=1.38\] \[1\times 1+2\times \frac{1}{10}+8\times \frac{1}{100}=1.28\] \[0\times 100+0\times 10+3\times 1+2\times \frac{1}{10}+5\times \frac{1}{100}+0\times \frac{1}{1000}\] Total cloths \[=0+0+3+\frac{2}{10}+\frac{5}{100}+0\] Hence, total cloths bought by Nasreen is 5.25 m.
