Solution in JavaScript (judge verdict: Accepted)

'use strict';
process.stdin.on('data', function(chunk) {
  var inputs = chunk.toString().trim().split(' ');
  var a = Number(inputs[0]);
  var b = Number(inputs[1]);

  console.log(a * b, (a + b) * 2);
});
process.stdin.resume();
process.stdin.setEncoding('utf8');
