Question

Nasreen bought $3m20cm$ cloth for her shirt and $2m5cm$ cloth for her trouser. Find the total length of cloth bought by her.

Answer 1

Given that:

Cloth bought by Nasreen for her shirt $=3m20cm$

Cloth bought by Nasreen for her trouser $=2m5cm$

Convert the unit of $m$ into $cm$:

We know that

$1m=100cm$

Therefore,

Cloth bought by Nasreen for her shirt $=3m20cm=(3\times 100)cm+20cm=320cm$

Cloth bought by Nasreen for her trouser $=2m5cm=(2\times 100)cm+5cm=205cm$

Now,

Total length of cloth bought by Nasreen $=$Cloth bought by Nasreen for her shirt $+$Cloth bought by Nasreen for her trouser

$=$$320cm+205cm=525cm$

$525cm$ can be written as $\left(5\times 100\right)cm+25cm=5m25cm$

Hence, the total length of cloth bought by Nasreen is $5m25cm$.
