int main()  /* main function*/

   printf("Enter length: ");  /* user's input */
   scanf("%d",&l);
   printf("Enter breadth: ");
   scanf("%d",&b);
   d = sqrt(pow(l,2) + pow(b,2)); /* calculate diagonal using Pifagor theorem */
   p = l*2 + b*2; /* perimeter */
   printf("Perimetr: %d, Diagonal: %f\n", p, d); /* prints perimeter and diagonal */
   system("pause");
