Main Answer:
The ruler measures 200 mm. Counting millimeter increments from the starting point provides an accurate length for precise measurements. C) 200 mm
Step-by-step explanation:
The correct measurement on the ruler is 200 mm. Each small division represents 1 mm, and by counting the divisions from the starting point to the end point, we arrive at a total of 200 mm. Rulers are commonly marked with millimeter increments, providing precision for various measurement needs.
Understanding ruler markings is essential for accurate measurements in fields such as science, engineering, and crafting. The ruler's longest line typically denotes the whole centimeters, and the shorter lines represent individual millimeters. In this case, the 200 mm measurement falls between the 19 cm and 20 cm marks.
It's crucial to pay attention to the ruler's zero point, ensuring that the measurement starts from the correct reference. Precision is key, especially when dealing with small units like millimeters. By correctly interpreting ruler markings, users can confidently determine lengths and dimensions for their projects or experiments.
In conclusion, the ruler in question displays a length of 200 mm. This measurement is obtained by counting the millimeter increments from the starting point to the end point on the ruler. Understanding how to read and interpret ruler markings is fundamental for accurate measurements in various fields.
Therefore, the correct answer is C) 200 mm.
