Question

Write a program in java to input the length and breadth of a rectangle and calculate its area and perimeter ​

Answer 1

Explanation:

import java.util.Scanner;

public class Area_Perimeter

{

public static void main(String[] args)

{

int l, b, perimeter, area;

Scanner s = new Scanner(System.in);

System.out.print("Enter length of rectangle:");

l = s.nextInt();

System.out.print("Enter breadth of rectangle:");

b = s.nextInt();

perimeter = 2 * (l + b);

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

area = l * b;

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

}

}

Output:

$ javac Area_Perimeter .java

$ java Area_Perimeter

Enter length of rectangle:4

Enter breadth of rectangle:5

Perimeter of rectangle:18

Area of rectangle:20
