Answer 2

Answering the Question

The question asks which width carpet would be suitable for a staircase with step lengths of 1 meter 2 decimeters (1.2 meters). It also asks what length of carpet would fully cover each step.

The optimal carpet width for these stairs would be 1 meter. According to my search, stair carpets are typically recommended to be 5-10 cm wider than the step length. For steps that are 1.2 meters long, a 1 meter wide carpet would allow for a few centimeters of overhang on each side.

A carpet that is 1.2 meters long would fully cover each step. Since the steps are 1.2 meters long, a carpet cut to this same length would extend from the front to the back of the step without any gaps.

Additional Context

The store carries carpets in a range of widths: 50 cm, 70 cm, 1 m, 1.2 m, 1.5 m, 2 m. Of these options, only the 1 m and 1.2 m widths would be suitable, with 1 m being the optimal choice to allow for overhang while not being too wide. Carpets are commonly recommended to be replaced when they show significant wear after 5-7 years of use on staircases. Proper installation is also important for safety, such as using adhesive or nails to prevent slipping.
