What are the three types of scale used in maps and plans, and provide examples for each?

Step 1: Identify the three types of scale from the given examples.
Based on the "Scale Representation" column in the table:

• Scale A (1 : 50 000) and Scale D (1 : 200) are examples of a ratio scale (or numerical scale/representative fraction).
• Scale B (a bar with segments representing 0, 5, 10 km) is an example of a graphic scale (or bar scale/linear scale).
• Scale C (1 cm = 2,5 km) is an example of a verbal scale (or statement scale).

The three types of scale used in maps and plans are:

• Ratio scale (or Numerical scale)
• Graphic scale (or Bar scale)
• Verbal scale (or Statement scale)

$$\boxed{\text{1.1 (i) The three types of scale are:}}$$ $$\boxed{\text{1. Ratio scale (or Numerical scale)}}$$ $$\boxed{\text{2. Graphic scale (or Bar scale)}}$$ $$\boxed{\text{3. Verbal scale (or Statement scale)}}$$
