Meterstick (0) 100 CM Printable Ruler | PDF - Free Printable

Based on the analysis of the image, the task is to understand how to use these printable rulers.

Here is the solution and explanation:

The image displays four separate, vertical metric rulers that are designed to be printed out and assembled into one long, continuous ruler.

- Ruler 1 (Leftmost): This ruler starts at 0 cm and goes up to 20 cm.
- Ruler 2: This ruler continues from where the first one ends, starting at 20 cm and going up to 40 cm. The URL "www.PrintableRulers.net" is visible on this ruler.
- Ruler 3: This ruler continues the sequence, starting at 40 cm and going up to 60 cm. It also has the same URL printed on it.
- Ruler 4 (Rightmost): This final ruler starts at 60 cm and goes up to 80 cm.

Solution:
To solve the problem, you need to print out all four rulers and physically align them end-to-end. When assembled correctly, they will form a single, continuous ruler that measures from 0 cm to 80 cm.

This is a common method for creating long rulers when you don't have access to a physical ruler of that length. The PDF icon in the top right corner indicates that this is a downloadable, printable document.

In summary, the task is not a mathematical problem to solve but rather an instruction to assemble the provided printable rulers to create a longer measuring tool.
