1. AREA OF TRAPEZIUM

2. A trapezium is a quadrilateral that has
only one pair of parallel sides.

3. HOW TO FIND THE AREA OF TRAPEZIUM?

4. To calculate the area of a
trapezium, divide it into a rectangle
and two triangles as shown below.

5. Now, piece together the triangular ends so that
the trapezium is divided into
a triangle and rectangle. The base of the
triangle is the difference between the lengths of
two parallel sides. That is, a – b

7. where
b1, b2 are the
lengths of each
base
h is the altitude
(height)
The area of a trapezoid is
given by the formula
