What is the property of form that characterizes an object or area with two dimensions?

The property of form that characterizes an object or area with two dimensions is referred to as shape. In the context of geometry and design, shape defines the outline or external form of an object, allowing it to be perceived and understood visually in a two-dimensional space. Shapes can be simple, like circles and squares, or complex, consisting of various combinations of lines and curves.

While size pertains to the dimensions or scale of the shape, it does not specifically define the form itself. Volume relates to three-dimensional objects, indicating how much space they occupy, thus it is not relevant in this context. Texture refers to the surface quality or feel of an object but does not contribute to the dimensional characteristics that define shape. Therefore, shape is the correct term to represent the two-dimensional nature of the property being discussed.
