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.
