Rombning diagonallari $d_{1}$ va $d_{2}$ berilgan. Diagonallar o'zaro perpendikular va kesishish nuqtasida teng ikkiga bo'linadi. Rombning yuzi $S$ va perimetri $P$ ni toping; $a$ — romb tomoni:
$$S = \frac{d_{1} * d_{2}}{2}, \qquad a = \sqrt{\left(\frac{d_{1}}{2}\right)^{2} + \left(\frac{d_{2}}{2}\right)^{2}}, \qquad P = 4 * a$$
Kiruvchi ma'lumotlar
Bitta qatorda ikkita natural son: $d_{1}$ va $d_{2}$.
Chiquvchi ma'lumotlar
Bitta qatorda ikkita son: $S$ — nuqtadan keyin aynan 1 ta raqam bilan (masalan, 24.0), $P$ — nuqtadan keyin aynan 3 ta raqam bilan (masalan, 20.000).
Izoh
$1 \le d_{1}, d_{2} \le 10^{4}$
