Автор ответа: katiy

рериметр равен (6+4)х2=20см

20/4=5см - сторона квадрата

5х5=25см кв - площадь квадрата

6х4=24см кв - площадь прямоугольника

25-24=1 см кв

Ответ на 1см кв

Автор ответа: momot

Р=2*(6+4)=20см периметр прямоугольника,
20/4=5см сторона квадрата,
S=5*5=25см² площадь квадрата,
S=6*4=24см² площадь прямоугольника,
25-24=1см² площадь прямоугольника меньше площади квадрата
