Help me in solving CLB009 problem

My issue

include <stdio.h>

int main(void) {
int l,b,Area,Perimeter;
l = 11;
b = 13;
Area = lb;
Perimeter = 2
(l+b);
printf(“Area of the rectangle is %d\n”,lb);
printf(“Perimeter of the rectangle is %d\n”,2
(l+b));
return 0;
}
so the above one was my code and the output is:
Area of the rectangle is 143
Perimeter of the rectangle is 48
when i have submitted the above code it showed me wrong output y?

My code

#include <stdio.h>

int main(void) {
    printf("%d\n",11*13);
	printf("%d\n",2*(11+13));
	return 0;
}
