Hint: Convert length of shirt and length of trouser to $cm$. Then to find the total length of cloth add the length of the shirt and length of the trouser. You will get the answer.

Length is the term used for identifying the size of an object or distance from one point to Length is a measure of how long an object is or the distance between two points. It is used for identifying the size of an object or distance from one point to another. The length of an object is its extended dimension, that is, its longest side.

The standard unit of length based on the metric system is a meter ($m$). According to the length that needs to be measured, we can convert a meter into various units like millimeters ($mm$), centimeter ($cm$), and kilometer ($km$).

Centimeters and millimeters help measure smaller lengths and meters and kilometers help measure larger lengths like distance. For example, the length of the pencils can be calculated in centimeters ($cm$), while kilometers can measure the distance between two buildings or places.

Length is a measure of distance. In the International System of Quantities, the length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units (SI) system the base unit for length is the meter.

Length is commonly understood to mean the most extended dimension of a fixed object. However, this is not always the case and may depend on the position the object is in.

So in the question, we have given that the length of cloth for her shirt is$3m20cm$ and for her trouser is $2m5cm$.

So now we want to find the total length of cloth bought by her.

So total length of cloth$=$ length of cloth for her shirt $+$ length of cloth for her trouser.

So now we must know the conversion.

$1m=100cm$.

So for the length of cloth for her shirt$=3m20cm=(3\times 100+20)cm=320cm$.

And for the length of cloth for her trouser$=2m5cm=(2\times 100+5)cm=205cm$.

So now the total length of cloth$=320cm+205cm=525cm=(500+25)cm=(5\times 100+25)cm=5m25cm$.

So we get the total length of cloth $525cm$or$5m25cm$.

Note: Read the question carefully. Don’t jumble yourself. You should know the conversion of $1m=100cm$. Most students make mistakes in conversion so avoid the mistakes. Don’t be confused. You should know how to calculate the total length.
