Solution in JavaScript (judge verdict: Accepted)

process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin.on('data', function (arrayStrig)
{
    arrayStrig = arrayStrig.split(' ');
    const a = Number(arrayStrig[0]);
    const b = Number(arrayStrig[1]);
    const area = a * b;
    const length =( a + b ) * 2;
    console.log(area + ' ' + length);
});
