Trapezoidal paving refers to a type of paving design where the stones or tiles used for the surface are laid in a trapezoidal pattern. This design is often used in public squares, walkways, and gardens for aesthetic and functional reasons. It can provide a visually appealing surface while also offering good drainage and stability. Central Square, as mentioned, would be a square located at the center of a town or city, where such a paving design might be implemented.
