Question

While measuring the length of a sheet of paper, the reading at one end of the scale was observed to be 1.5 cm and at other end it was found to be 18 cm. Find the length of the sheet.

Answer 1

Answer:

length = 18 - 1.5 = 16.5 cm

Normally scale starts from zero. But here scale starts from 1.5, that is why you subtract the initial reading.
