C Program to Find Area of a Rectangle

Write a C program to input length and width of a rectangle and find area of the given rectangle.

Here, you can see that we will find Area of Perimeter. The amount of space inside a shape is called Area. The Formula for the Area of a rectangle is Area = Length * Breadth . The standard unit of area is square units which is generally represented as square inches, square feet, etc. The distance around the edge of a shape is called perimeter. The Formula for the Perimeter of a rectangle is Perimeter = 2(Length + Breadth).

Inside the program, first of all we find the area of the perimeter in the C program. After that, by finding the area of the perimeter, we can find out which of the two has a larger area.

Code:

// Find Area of Perimeter and 
// check who's greater
#include <stdio.h>
int main()
{
  float langth ,breadth;
  
  printf("Enter length: ");
  scanf("%f", &length);
  
  printf("Enter breadth: ");
  scanf("%f", &breadth);

  // Calculate area
  float area = langth * breadth;
  
  // Calculate perimeter
  float peri = 2 * (langth + breadth);

  // Output the results
  printf("Area of the Rectengle: %.2f\n",area);
  printf("Perimeter of the Rectangle: %.2f\n",peri);
  
  // Compare area and parimeter
  if (area > peri)
  {
    printf("\n The area is greater than the perimeter.");
  }
  else if (peri > area)
  {
    printf("\n The perimeter is greater than the area.");
  }
  else
  {
    printf("\n The area and parimeter are equal.");
  }
  return 0;
}

Output:

Enter length: 14
Enter breadth: 12

Area of the Rectengle: 168.00
Perimeter of the Rectangle: 52.00

The area is greater than the perimeter.
