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)
}


## Output

The sides of the rectangle are defined as 5, 8, 5, 8
Perimeter of rectangle is: 26
