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. Select the correct answer from above options

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) ; } }
