Shapes.

Explanation:

Shapes has two-dimensions, height and width, and are usually defined by lines.

This ultimately implies that, height (length) and width (breadth) are the two dimensional quantities that makes up a shape. Also, the shape of any physical object is directly defined by either straight or curved lines depending on the type of object.

Some examples of shapes in science or art are rectangle, circle, polygon, square, cylinder, cone, sphere, etc.

Additionally, shapes in art can either be geometric or organic.
