Периметр квадрата в 2 раза больше периметра прямоугольника. Чему равна длина стороны этого квадрата, если длины сторон прямоугольника равны 4 см и 2 см?

Ответы

Автор ответа: VoinGood

P(прямоугольника)= (4+2)*2= 12 (см);
P(квадрата)= 12* 2= 24 (см);
В квадрата все стороны равны. Значит:
24/ 4= 6 (см) - сторона квадрата.
