In this tutorial you will learn about the C Program to find Area & Perimeter of Rectangle and its application with practical example.
C Program to find Area & Perimeter of Rectangle
In this tutorial, we will learn to create a C program that will find the Area & Perimeter of Rectangle in C programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following C programming topics:
- Operators in C Programming.
- Basic Input and Output function in C Programming.
- Basic C programming.
- While loop in C programming.
Program to find Area & Perimeter of Rectangle:-
As we all know the c is a very powerful language. With the help of c programming language, we can make many programs. We can perform many input-output operations using c programming. In today’s tutorial, we take the input in the form length and width of the Rectangle. Then we will find its area and parameter with the help of the c programming language.
With the help of this program, we can find the Area & Perimeter of the Rectangle.
Algorithm:-

1. Declare the variables for the program. 2. Takeing the input length and widthof the <strong>Rectangle </strong>from the user. 3. Passing that input number to calculate the perimeter. 4. Passing that input number to calculate the area. 4. Print the Result. 5. End the program. |

/* C Program to find area and perimeter of a Rectangle */ #include <stdio.h> int main() { /* Declaring the variable for the program for storing the data */ float lgth,wdth, perimeter,area; //lgth = to store the length of the side of rectangle //wdth = to store the width of the side of rectangle //perimeter = to store the side of the perimeter //area = to store the side of the area /* Taking the input length of the rectangle from the user */ printf("Enter length of Rectangle\n"); scanf("%f", &lgth); /* Taking the input width of the rectangle from the user */ printf("Enter width of Rectangle\n"); scanf("%f", &wdth); /* Calculating Perimeter of Rectangle = 2 (length + width) */ perimeter = 2*(lgth+wdth); printf("Perimeter of Rectangle : %0.4f\n", perimeter); /* Calculating Area of Rectangle = length * width */ area = lgth*wdth; printf("Area of Rectangle : %0.4f\n", area); return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- lgth = it will hold the float value.
- wdth = it will hold the float value.
- area = it will hold the float value.
- perimeter = it will hold the float value.
Taking the input from the message.
