85,75см²
Пошаговое объяснение:
Формула нахождения площади квадрата
S=a²
Найдем сторону большого квадрата
a=√S=√196=14 см сторона квадрата.
Теперь найдем сторону маленького квадрата.
14:4=3,5см сторона маленького квадрата.
Sм.кв=3,5²=12,25 см² площадь маленького квадрата.
Всего маленьких квадратов 7
12,25*7=85,75 см² площадь закрашенной части
Фигура состоит из 16 маленьких квадратов.
196:16=12,25 см² площадь одного маленького квадрата.
Закрашенная часть состоит из 7 маленьких квадратов.
12,25*7=85,75 см² площадь закрашенной фигуры.
