A 20 cm square is a shape with all four sides measuring 20 cm, creating a perfect square. It has an area of 400 square centimeters. In contrast, an 18 cm measurement could refer to either the length of a side of a square (which would have an area of 324 square centimeters) or the length of a rectangle. Visually, the 20 cm square appears larger than the 18 cm measurement, whether it’s a square or another shape.
