This C example program performs simple mathematical calculations to find the area and perimeter of a rectangle. The perimeter of a rectangle is equal to 2 times the length + width, and its area equals the multiplication of length and width.
Example C Program:
#include <stdio.h>
void main() {
/* Variable Declaration. */
float lnth, wdth, perimeter, area;
/* Taking input of the length of the rectangle from the user */
printf("Enter the length of the Rectangle:\n");
scanf("%f", & lnth);
/* Taking input of the width of the rectangle from the user */
printf("Enter the width of the Rectangle:\n");
scanf("%f", & wdth);
/* Calculate perimeter of the rectangle */
perimeter = 2 * (lnth + wdth);
printf("Perimeter of the Rectangle: %0.4f\n", perimeter);
/* Calculate area of the rectangle */
area = lnth * wdth;
printf("Area of the Rectangle: %0.4f\n", area);
}
Program Output:
Enter the length of the Rectangle: 50 Enter the width of the Rectangle: 80 Perimeter of the Rectangle: 260.0000 Area of the Rectangle: 4000.0000
