<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.
