It is also known as trapezium. It is a quadrilateral shape which has a pair of parallel sides.

## Properties of Trapezoid

- Known as trapezium in UK.
- It has a pair of parallel sides.
- Parallel sides are called bases of trapezoid.

## Area of Trapezoid

The area of trapezoid is given by:

*A=h.[(a + b)/2]*

Where, ** a **and

**are the two bases of trapezoid,**

*b***is the height.**

*h*## Parameter of Trapezoid

Parameter of trapezoid is the sum of the length of all sides.

*P= a + b + c + d*

## Median of Trapezoid

The median of a trapezoid is the midline halfway between the two bases.

*m= (a + b)/2*
