Solution in JavaScript (judge verdict: Accepted)

const main = (standardInput) => {
    const lengthList = standardInput.split(' ');
    const varticalLength = Number.parseInt(lengthList[0]);
    const horizonLength = Number.parseInt(lengthList[1]);

    console.log(`${varticalLength * horizonLength} ${2 * (varticalLength + horizonLength)}`);
}

main(require('fs').readFileSync('/dev/stdin', 'UTF-8'));
