Correct Answer: Option 2 90mm

Approximation or estimation typically means finding upper or lower bounds of a quantity that cannot readily be computed precisely and is also an educated guess. Since we are limited by the ruler, we will just estimate the length of the earthworm based on the number of centimeters covered. One centimeter is composed of 10 millimeters. Based on the diagram, the earthworm covered 9cm which is equal to 90mm.
