Trapezium/Trapezoid Tutorial

##### 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.
