Question

Найдите площадь и периметр 2/3 прямоугольника Периметр которого 34 см а длина 11 см

Answer 1

Ответ: ширина прямоугольника 6см

площадь равна 66см²

Пошаговое объяснение:                        

11*2=22                                    6*11=66

34-22=12

12/6=2

(6+6)+(11+11)=12+22=34

To answer your question, I will use the web search results from my internal tool.

The area and perimeter of a rectangle are calculated by the formulas: $$S = a \cdot b$$ and $$P = 2(a + b)$$, where $$a$$ and $$b$$ are the length and width of the rectangle.

To find the area and perimeter of $$2/3$$ of a rectangle, we need to multiply the original area and perimeter by $$2/3$$.

The original area of the rectangle is $$S = 11 \cdot b$$, where $$b$$ is the unknown width.

The original perimeter of the rectangle is $$P = 34$$, according to the problem statement.

We can use the perimeter formula to find the width: $$34 = 2(11 + b)$$, which implies $$b = 6$$.

Therefore, the original area of the rectangle is $$S = 11 \cdot 6 = 66$$ cm$$^2$$.

The area of $$2/3$$ of the rectangle is $$2/3 \cdot S = 2/3 \cdot 66 = 44$$ cm$$^2$$.

The perimeter of $$2/3$$ of the rectangle is $$2/3 \cdot P = 2/3 \cdot 34 = 22.67$$ cm.

I hope this helps.
