Kotlin Program To Find The Area of a Trapezium

In this article, we will understand how to find the area of a trapezium. The area of a trapezium is calculated using the formula.

(height/2 * (side1 + side2))

Below is a demonstration of the same ?

Suppose our input is ?

side1 = 5
side2 = 6
height = 6

The desired output would be ?

Area of trapezium is: 33.0

Algorithm

• Step 1 ? START.

• Step 2 ? Declare four integer values namely side1, side2, height and myResult.

• Step 3 ? Define the values.

• Step 4 ? Calculate the area of the trapezium using the formula (height/2 * (side1 + side2) and store the result.

• Step 5 ? Display the result.

• Step 6 ? Stop.

Example 1

In this example, we will find the Area of a Trapezium with the sides and height of the trapezium. First declare and initialize the variables for the sides and height.

val side1 = 5
val side2 = 6
val height = 6

Now, find the Area of a Trapezium using the above formulae ?

val myResult = (height/2 * (side1 + side2));

Let us now see the example to find the Area of a Trapezium ?
