Answer:
importJava.util.*
public class Area
{
public static void main(int a)
{
Scanner sc=new Scanner(System.in)
System.out.println("write 1 for circle 2 for square and 3 for rectangle");
if(a==1)
{
double w=sc.nextInt();
double area=double Circle(w);
System.out.println(area);
}
else if(a==2)
{
int e=sc.nextInt();
double area=int Square(e);
System.out.println(area);
}
else if(a==3)
{
int j=sc.nextInt();
int h=sc.nextInt();
double area=int rectangle(j,h);
System.out.println(area);
}
}
public static int Square(int s)
{
double x=Math.pow(s,2);
return x;
}
public static double Circle(double r)
{
double y=(22/7)*Math.pow(r,2);
return y;
}
public static int rectangle(int l;int b)
{
double q=l*b;
return q;
}
}
}
