area is l*b
no need to guide user for entering length and breadth.
just take input and produce output.

#include <stdio.h>

int main() {
    int length, width;
    int area;
    
    scanf("%d", &length);
    scanf("%d", &width);
    
    // calculate area and print area
    area=length*width;
    printf("Area of the rectangle is: %d",area);
}
