All the lengths of carpet are laid on the height and length of stairs, so the sum of the height and length of stairs is the length of carpet.

Move all stairs to the far right, and the height of all stairs is 3 meters.

Translate the length of all the stairs to the end, and all the stairs are 5 meters long.

So the total length of the carpet is 8 meters.

Characteristics of translation:

Before and after 1. translation, the shape and size of the graph remain unchanged, but the position has changed.

2. The line segments connected by the corresponding points of the new figure and the original figure are parallel and equal (or on the same straight line).

3. After translation, the corresponding line segments are parallel (or * * * lines) and equal, the corresponding angles are equal, and the line segments connected by the corresponding points are parallel and equal.

4. Translation is often related to parallel lines. Translation can translate an angle, a line segment and a figure to another position, which is the concentration of scattered conditions on a figure, thus solving the problem.
