Kotlin Program to Find the Perimeter of a Rectangle
In this article, we will understand how to find the perimeter of a rectangle. The Perimeter of a rectangle is calculated using the following formulae
2*(length + width)
Below is a demonstration of the same −
Suppose our input is
The length of the sides of a rectangle are: 5, 8, 5, 8
The desired output would be
Perimeter : 26
Algorithm
Step 1 − START
Step 2 − Declare three integer variables length, width and myResult.
Step 3 − Define the values.
Step 4 − Calculate the perimeter using the formula 2 * (length + width), store the output in myResult
Step 5 − Display the Perimeter value
Step 6 − STOP
Example 1
In this example, we will find the Perimeter of a Rectangle using the above given formulae. First, declare and set the variables length and width −
val length = 5 val width = 8
Then, find the Perimeter of Rectangle using the length and width
val myResult = 2 * (length + width)
Let us see the example to calculate the Perimeter of Rectangle −
fun main() { val length = 5 val width = 8 println("The sides of the rectangle are defined as $length, $width, $length, $width") val myResult = 2 * (length + width) println("Perimeter of rectangle is: $myResult") }
Output
The sides of the rectangle are defined as 5, 8, 5, 8 Perimeter of rectangle is: 26
Example 2
In this example, we will find the perimeter of a Rectangle
fun main() { val length = 5 val width = 8 println("The sides of the rectangle are defined as $length, $width, $length, $width") getPerimeter(length, width) } fun getPerimeter(length: Int, width: Int) { val myResult = 2 * (length + width) println("Perimeter of rectangle is: $myResult") }
Output
The sides of the rectangle are defined as 5, 8, 5, 8 Perimeter of rectangle is: 26
