Problem Analysis:
The image shows a ruler with markings and an arrow pointing to a specific position. The task is to determine the exact measurement indicated by the arrow.
Step-by-Step Solution:
1.
Identify the Scale of the Ruler:
- The ruler is marked in centimeters (cm), as indicated by the larger numbered ticks.
- Between each centimeter mark, there are smaller ticks representing millimeters (mm). Since 1 cm = 10 mm, each small tick represents 1 mm.
2.
Locate the Arrow:
- The arrow is pointing between the 1 cm and 2 cm marks.
- Specifically, the arrow is aligned with the second small tick after the 1 cm mark.
3.
Determine the Measurement:
- The first small tick after the 1 cm mark represents 1.1 cm.
- The second small tick after the 1 cm mark represents 1.2 cm.
- Since the arrow is pointing directly at the second small tick, the measurement is
1.2 cm.
Final Answer:
$$
\boxed{1.2}
$$
This solution is based on the clear markings and scale of the ruler, ensuring accuracy in determining the measurement.
