8. While taking a measurement, Ajay put the 2nd mark of the scale to the edge of the line and the mark that pointed to the end of the line was 80 cm. What is the total length of the line? Write the length of line in meter also.

The length of line is 78 cm or 0.78 m.

Explanation:

initial reading 2 mark

final reading 80 cm

The length of the line

= final reading - initial reading

1 cm = 0.01  m

So, 78 cm = 0.78 m
