C Program to Calculate Area of Rectangle

C Program for Beginners : Area of Rectangle

---

Shape : Rectangle

formula : area = l * b

Definition

1. A plane figure with 4 sides and 4 right angles and having Equal Opposite Sides
2. Adjucent sides makes an angle of 90 degree
   
3. You can compute the area of a Rectangle if you know its length and breadth

Program :

#include<stdio.h>
#include<conio.h>

void main()
{
int length,breadth,side;
clrscr();  // Clear Screen

printf("nEnter the Length of Rectangle : ");
scanf("%d",&length);

printf("nEnter the Breadth of Rectangle : ");
scanf("%d",&breadth);

area = length * breadth;

printf("nArea of Rectangle : %d",area);
getch();
}

Output :

Enter the Length of Rectangle  : 5
Enter the Breadth of Rectangle : 4
Area of Rectangle : 20
