Стороны в четыреугольнике относятся 2:3:3:4 при этом самая большая сторона = 20, найти периметр

Ответы

Автор ответа: theoreticalphysicist

Составляем уравнение
$2x+3x+3x+4x=P \\ 12x=P$
Большая сторона - 4x, следовательно:
$4x=20 \\ x = 5$
Тогда:
$P=12x=12\cdot5=60$

AndrewKuzmenko: Спасибо, странно что я это не решил

theoreticalphysicist: Ничего, иногда бывает
