15×12

15x12 refers to a common rectangular dimension, often used to describe the size of objects or spaces. This measurement indicates a width of fifteen units and a height or depth of twelve units. The specific units of measurement, such as inches, feet, centimeters, or pixels, are usually implied by the context in which "15x12" is used.

For example, in construction or interior design, 15x12 might describe the dimensions of a room, a window, or a piece of furniture. In graphic design or digital media, it could represent the resolution of an image or the dimensions of a screen. The term is a concise way to communicate a standard rectangular shape without needing to explicitly state "width" and "height" each time, assuming the order is understood. This convention is widely recognized in various industries and everyday applications.
