In a quadrilateral, half of the product of the sum of the lengths of parallel sides and the distance between them gives the area of a ______.
In a quadrilateral, half of the product of the sum of the lengths of parallel sides and the parallel distance between them gives the area of a trapezium.
Area of trapezium ABCD=12× (Sum of parallel sides) × perpendicular distance between them
=12×(b1+b2)×h
