Answers of the students are likely to be different. Length of cloth needs to be measured up to a millimetre (mm) length.
Hence, to obtain accurate and precise reading one must use measuring instrument having least count smaller than 1 mm.
But least count of metre scale is 1 mm. As a result, even smallest uncertainty in reading would vary reading significantly. Also, skill of students doing measurement may also introduce uncertainty in observation. Hence, their answers are likely to be different.
