3 сторона - 3 целых 29/60 см.
Найдите периметр треугольника? пожалуйста помогите

Ответы

Автор ответа: ExtaVvV

2,1 метр = 2 1/10
1) 7 11/30 + 2 1/10 + 3 29/60 = 7 22/60 + 2 6/60 + 3 29/60 = 12 57/60
Ответ: Периметр треугольника = 12 57/60
ЕСЛИ МОЖНО ПОСТАВЬ ПОЖАЛУЙСТА ЛУЧШИЙ ОТВЕТ

ExtaVvV: Пожалуйста)

abdullayevnematilla8: не знаете ли вы как сделать лучшим ответом

abdullayevnematilla8: а тут ошибка

abdullayevnematilla8: я написала на 2,1 метр меньше чем 1 сторона

ExtaVvV: Не знаю

ExtaVvV: Просто от моего ответа отними 2 1/10

ExtaVvV: Если точнее

ExtaVvV: 10 51/60

abdullayevnematilla8: спасибо большое
