Answer:
Explanation:
The instrument used to measure length on a map is called a scale or a map scale. A map scale is a line or bar that represents a specific distance on the ground. It is typically found in the legend or key of a map. The scale is used to convert the distances on the map to real-world distances. To measure length on a map using a map scale, follow these steps: 1. Locate the map scale in the legend or key of the map. 2. Determine the unit of measurement used on the scale, such as kilometers or miles. 3. Identify the length you want to measure on the map. 4. Place a ruler or straight edge along the length you want to measure. 5. Align one end of the ruler with the beginning of the length and read the measurement on the map scale where the other end of the ruler intersects the scale. 6. Convert the measurement on the map scale to the corresponding real-world distance using the unit of measurement specified on the scale. For example, let's say you have a map scale that represents 1 centimeter on the map as 1 kilometer in real-world distance. If you measure a length on the map as 3 centimeters using a ruler, then the corresponding real-world distance would be 3 kilometers
