Area is the quantity that expresses the extent of a two-dimensional figure or shape, orplanar lamina, in the plane. Surface area is its analog on the two-dimensional surface of athree-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat.[1] It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).
A trapezium, also known as a trapezoid, is a quadrilateral in which a pair of sides are parallel, but the other pair of opposite sides are non-parallel. The area of a trapezium is computed with the following formula:
The parallel sides are called the bases of the trapezium. Let and be the lengths of these bases. The distance between the bases is called the height of the trapezium. Let be this height. Then this formula becomes:
Trapezium, describing a geometric shape, has two contradictory meanings:
