Length And Width
Area; this is often measured in square meters, or square centimeters.
zero-dimensional examples: Endpoints of edges (vertices and corners) Zero-dimensional figures lie in two-dimensional planes. one-dimensional examples: Edges of figures (sides and arcs) One-dimensional figures lie in two-dimensional planes.
No, they are two-dimensional.
Plane figures.
zero. two dimensional figures do not occupk any space
Plane figures
Area. Very few 2-dimensional figures can be measured by length and width - rectangles (and stretching the terminology) triangles and parallelograms. Certainly not circles, stars, irregular polygons, other irregular shapes.

a two dimensional figure is flat. it only has length and width. three dimensional figures have length, width and height. A square is a 2 dimensional figure, but a cube is a 3 dimensional figure.
Two three dimensional figures that have circular bases: Cone, and Cylinder.
For example, if you keep on stacking squares (two dimensional figure) on top of one another, it will slowly form a cuboid (three dimensional figures). There is a mathematical way of calling it. Google it!
