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.

Solution:

Length of cloth in metres bought for the shirt = m cm = (3 + 20100) m = 3.203.30 m

Length of cloth in metres bought for the trouser = m cm = (2 + 5100) m = 2.052.50 m

So, total length of cloth bought by her = 3.203.30 m + 2.052.50 m = 5.255.55 m
