Area of Trapezium:
A trapezium is a quadrilateral with two parallel bases and two equal heights. It is a versatile geometric shape with a rich history and diverse applications.
The area of a trapezium is calculated using the formula:
A = (b1 + b2) * h / 2
where:
A is the area of the trapezium
b1 and b2 are the lengths of the parallel bases
h is the height (or altitude) of the trapezium
Important Points:
The area of a trapezium is always greater than the area of a rectangle with the same bases and height.
The area of a trapezium is also greater than the area of a triangle with the same bases and height.
The area of a trapezium is independent of the angle between the bases.
The perimeter of a trapezium is equal to the sum of the lengths of all four sides.
Examples:
A rectangle with dimensions 5 cm and 10 cm has an area of 50 cm².
A triangle with dimensions 6 cm, 8 cm, and 10 cm has an area of 48 cm².
A trapezium with bases 8 cm and 10 cm and a height of 6 cm has an area of 40 cm².
The area of a trapezium can be used for various purposes, including finding the area of a flat surface, calculating the volume of a 3D object, and determining the force required to lift an object
