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

Solution in C# (judge verdict: Accepted)

using System;

class Rectangle {
    public static void Main() {
        string Input_Str = Console.ReadLine();
        string[] Input_Num = Input_Str.Split(' ');
        int a = int.Parse(Input_Num[0]);
        int b = int.Parse(Input_Num[1]);
        int area = a * b;
        int length = a * 2 + b * 2;
        Console.WriteLine(area + " " + length);
    }
