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
