<u>Answer :-</u> <em>Option 2</em> 90 mm is correct.

<u>Explanation :-</u>

  • In the given diagram, we consider the starting point of measurement the value where the mouth of the earthworm is pointed i.e 1.5 cm.
  • So if we count from 1.5 cm that is the start point and then we see the end point i.e 10.5 cm we get,

10.5 - 1.5 = 9.0 cm

So the length of the earthworm is 9.0 cm as seen from the scale.

  • Now to convert cm into mm, we need to know that:

1 cm = 10 mm

Thus, to convert 9.0 cm to mm

we need to multiply 9 by 10

9 X 10 = 90

So the answer is 90 mm.
