Reason: 2 Marks
Problems: 3 Marks
Since the tape is stretchable and when you will measure anything it will give inaccurate measurements. Therefore we cannot use it for measuring purposes.
Problems:
1. While measuring a distance, we need to tell someone how much tape has been stretched which is difficult to measure. It leads to incorrect measurements.
2. We cannot measure manually how much the tape has been stretched.
3. If you measure the length of an object twice using an elastic tape, then you may get different values of the same length each time. This is because elastic tapes are stretchable.
