Question

answer how to measure length with the broken ruler

Answer 1

if the broken scale measures 7 cm then after 7 cm go back again to 1 and leave 0 and start measuring If ur length is 13 cm it will be like 7 +6 cm which is 13 cm

Answer 2

Answer:

If the ends of a ruler are broken and the zero or any other mark cannot be seen clearly , avoid taking the measurement from zero or any other mark which is broken. Instead begin with any other full mark of the scale, say, 1.0 CM. Then, subtract the reading of this mark from the reading at the another end. For example if you begin at 1.0 and ends at 14.3 CM the length of the object would be:-

14.3 - 1.0 CM = 13.3 CM ←ans.
