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
int len, br, area;
printf("Enter the length: ");
printf("Enter the breadth: ");
area = len * br;
printf("Area of a rectangle: %d", area);
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.
