Create a class called Trapezium, which is determined by two parallel sides “a” and “b” and the height “h” between them.The area of the trapezium can be calculated as Area = (a+b)h/2 The perimeter = a + b + 2 sqrt[{h2 + (b-a)2/4}] Add this class to your project and add a couple of them to your object array.

So I want to stop the cursor …
