Solution in JavaScript (judge verdict: Accepted)

'use strict';
(function(stdin) {
  var inputs  = stdin.toString();
  var flines = inputs.split('\n')[0].split(' ').map(Number);
  var a = flines[0];
  var b = flines[1];
  var area = a * b;
  var periphery = 2 * (a + b);

  console.log(area,periphery);
