Solution in JavaScript (judge verdict: Accepted)

process.stdin.resume()
process.stdin.setEncoding('utf8')
process.stdin.on('data', function (chunk) {
  const input = chunk.split(' ').map(Number)
  const area = input[0] * input[1]
  const outer = input[0] * 2 +  input[1] * 2
  console.log(area + ' ' + outer)
})
