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.​ DO NOT USE ANY INPUT METHOD​

Answer 1

Answer:

public class area_perimeter

{

public static void main(String[]args)

{

int s = 20;

//example for side is 20

int ln= 40;

//example for side is 40

int b=30;

//example for side is 30

int area_square , area_rectangle , perimeter_square , perimeter_rectangle,area_square = s*s ;

area_rectangle = ln*b ;

perimeter_square = 4*s;

perimeter_rectangle = 2*(l+b);

System.out.println("area of the square=" + area_square);

System.out.println("area of the rectangle="+area_rectangle);

System.out.println("perimeter of the square="+perimeter_square);

System.out.println("perimeter of the rectangle="+perimeter_rectangle);

}

}
