How do you find an area of a trapezium?
The area of a trapezium is given by A = ( a + b ) 2 × h . You can see that this is true by taking two identical trapezia (or trapeziums) to make a parallelogram. Turn one trapezium through 180°. Use the perpendicular height of the trapezium, not the sloping height.
