Trapezium Definition:
A trapezium is a shape with four sides, that has one set of parallel sides.
Trapezium/Trapezoid Formula:
Area of Trapezium = ½×(a + b)×h
where
a, b = sides, h = height
Perimeter of Trapezium = a + b + c + d
where
a, b, c, d = sides

Trapezium/Trapezoid Example:
Case 1: Find the area of a trapezium using the sides length as 3, 4 and the height 2.
Step 1: Find the area.
Area = ½ * (a + b) * h = ½ * (3 + 4) * 2 =
½ * 7 * 2 = 7.
Case 2: Find the perimeter of a trapezium using the sides length as 3, 4, 5, 6.
Step 1: Find the perimeter.
Perimeter = a + b + c + d = 3 + 4 + 5 + 6 = 18.
The above example will clearly illustrates how to calculate the Area and Perimeter of a Trapezium manually.
