C Program to Find Perimeter of a Rectangle

In this article, we are going to understand and implement a simple C program, to find the perimeter of the rectangle. To calculate the perimeter of a rectangle is very easy using a C program, provided that you are already familiar with the simple formula to calculate the perimeter of a rectangle, and you know how to write C programs.

C Program to Find Perimeter of a Rectangle

In the given video, you can find an easy explanation along with the simple C program to find the perimeter of a rectangle.

The perimeter of a rectangle can be simply calculated as the sum of all the sides of the rectangle. Here is the formula for calculating the perimeter of a rectangle.

P=2(l+w)

Here, l is the length, w is the width, and P is the perimeter of the rectangle. So, having the length and the width, you can easily calculate the perimeter of the rectangle.

Here is the C program to calculate the perimeter of the rectangle –

#include <stdio.h>

int main() {
float length, width, perimeter;

// Input the length and width of the rectangle
printf("Enter the length of the rectangle: ");
scanf("%f", &length);

printf("Enter the width of the rectangle: ");
scanf("%f", &width);

// Calculate the perimeter of the rectangle
perimeter = 2 * (length + width);

// Print the perimeter
printf("Perimeter of the rectangle: %.2fn", perimeter);

return 0;
}

Output 1 –
Enter the length of the rectangle: 5
Enter the width of the rectangle: 2
Perimeter of the rectangle: 14.00

Output 2 –
Enter the length of the rectangle: 15
Enter the width of the rectangle: 6
Perimeter of the rectangle: 42.00
