Answer 1

No it doesn't work

Answer 2

here it is i have corrected it for you. go through it.
// area of rectangle //
import java.util.Scanner;
class AreasOfShapes
{
public static void main(String[] args){
Scanner s= new Scanner(System.in);

double l,b;
l=s.nextDouble();
b=s.nextDouble();
if(l>0&&b>0)
{

System.out.println("Area Of Rectangle");

System.out.println("Enter length of Rectangle :"+l);

System.out.println("Enter Breath of Rectangle :"+b);

double area= l*b;

System.out.println("Area Of Rectangle Is :"+area);}

else{System.out.println("enter valid number");
}
}
}
