Question

Write a JAVA program to find the area and perimeter of a square and rectangle. Store side in s , length as 'ln' and breadth as 'b'. display the results in separate lines.​

Answer 1

Explanation:

import java. util. *;

class Sqrec

{

public static void main (String args[])

{

Scanner in =new Scanner(System.in) ;

System. out. println( "Enter side of square");

int s=in.nextInt() ;

System. out println( " Enter length of rectangle") ;

int ln = in. nextInt() ;

System. out. println(" Enter breadth of rectangle ") ;

int b=in.nextInt() ;

int a1=0;

int a2=0;

int p1=0;

int p2=0;

a1= s*s;

a2=ln*b;

p1= 4*s;

p2= 2*(ln +b) ;

System. out. println( "Area of square : "+a1) ;

System. out. println(" Perimeter of square : "+ p1) ;

System. out. println("Area of rectangle :" + a2) ;

System. out. println ("Perimeter of rectangle :" + p2) ;

}

}
