Ответ:

16 см

Пошаговое объяснение:

Давайте спочатку знайдемо довжину прямокутника.

Ширина прямокутника 2 см, і це у 3 рази менше від довжини. Запишемо це в рівнянні:

2 см = (1/3) * довжина

Тепер ми можемо знайти довжину прямокутника, помноживши обидві частини рівняння на 3:

2 см * 3 = довжина

6 см = довжина

Тепер, коли ми знаємо ширину і довжину прямокутника, ми можемо знайти периметр трикутника.

Периметр трикутника складається з суми довжин усіх його сторін. Але у нас немає жодних даних про сторони трикутника. Ймовірно, у питанні виникла помилка, і вам потрібно знайти периметр прямокутника, а не трикутника.

Якщо це так, то периметр прямокутника розраховується за формулою:

Периметр = 2 * (довжина + ширина)

Замінюємо значення:

Периметр = 2 * (6 см + 2 см)

Периметр = 2 * 8 см

Периметр = 16 см

Отже, периметр прямокутника дорівнює 16 см.
