- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/150-square-cut-into-strips/0/) — When a square is cut by parallel cuts into equal strips, every strip is as long as the square's side, and its width is the side divided by the number of strips.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/150-square-cut-into-strips/1/) — So the perimeter of a strip is two sides of the square and two widths: if there are 3 strips, the half-perimeter of a strip is one side and one third of a side, that is 4 thirds of the side.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/150-square-cut-into-strips/2/) — For 3 strips with a perimeter of 16 cm each: half is 8 cm = 4 widths, so a width is 2 cm, the side is 3 × 2 = 6 cm and the square's perimeter is 4 × 6 = 24 cm.
