Rectangle

Write a program which calculates the area and perimeter of a given rectangle.

Input

The length a and breadth b of the rectangle are given in a line separated by a single space.

Output

Print the area and perimeter of the rectangle in a line. The two integers should be separated by a single space.

Constraints

1 ≤ a, b ≤ 100

Sample Input 1

3 5

Sample Output 1

15 16

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main{

	public static void main(String args[]){
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int b = sc.nextInt();

		int area = a * b;
		int perimeter = 2*(a + b);

		// String input = sc.nextLine();
	  // String nums[] = input.split(" ");

	  // long A = Long.parseLong(nums[0]);
	  // long B = Long.parseLong(nums[1]);
	  // long sum = Long.parseLong(nums[2]);

		System.out.println(area + " " + perimeter);
		// System.out.println(S.toString());

	}
