Geometry Definitions
The following is a list of definitions relating to the area of a trapezium.
What is area?
Area is the size of a surface.
What is a trapezium?
A trapezium (as defined in the UK) is a two-dimensional shape that is a quadrilateral with one pair of sides that are parallel.
Geometry Formula
The formula to calculate the area of a trapezium is:
A = ½(a+b) x h
where...
- A = area of trapezium
- a = top of parallel sides of trapezium
- b = base of parallel sides of trapezium
- h = height of trapezium
