उत्तर
Given, the length of the pencil is 2.6 cm.
We can presume that the length was measured using the metre rule because it is expressed in centimetres to one decimal place.
Therefore, the measurement is precise.
The length cannot be expressed as 2.60 cm because a metre scale measures length correctly only up to one decimal place of a centimeter.
