length of pencil ​

Answer 1

Step-by-step explanation:

When measuring the length of the pencil, it is not a must that we start from the zero mark. This question shows that we can even use a broken ruler to measure the length of object. To get the length of the object, we subtract the initial reading from the final reading. The length of the pencil = 12.1 - 2.0 = 10.1 cm ..The pencil measures 10.1 cm

Answer 2

Answer:

14.4

Step-by-step explanation:

The reading of scale from one end = 2.0 cm

The reading of scale from the other end= 16.4 cm

The length of pencil= The reading of scale from the other end- The reading of scale from one end

= 16.4 cm - 2.0 cm

= 14.4 cm
