C Program to Find the Area of a Rectangle

In this tutorial, we will write a C program to find the area of a rectangle. Before that, you may go through the following topic in C.

Explanation: The program asks the user to enter the value of length and breadth as an input. Then simply using the formula (area = length * breadth), we calculate the area of a rectangle in C.


C Program to find the area of a Rectangle

#include <stdio.h>

int main()
{
  int len, br, area;

  printf("Enter the length: ");
  scanf("%d", &len);
  printf("Enter the breadth: ");
  scanf("%d", &br);

  area = len * br;
  printf("Area of a rectangle: %d", area);

  return 0;
}

Output:

Enter the length: 2
Enter the breadth: 5
Area of a rectangle: 10

You may change the data type int to float or any other as per your requirements.
