Question

Задача №15 Ширина прямоугольника 8 см. Чему равна длина, если периметр 36 см?​

Answer 1

Ответ:

10 см

Пошаговое объяснение:

36- (8×2) = 36 - 16 = 20 : 2 = 10

Answer 2

Ответ:

Длина = 10см

Пошаговое объяснение:

P= a+b+c+d

Ширина это a+c

Длина это b+d

8+8=16

36-16 =20

20:2=10

Ответ: 10см

Answer 3

Problem:

The width of a rectangle is 8 cm. What is the length if the perimeter is 36 cm?

Solution:

To find the length of the rectangle, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (Length + Width)

In this case, we are given that the width of the rectangle is 8 cm and the perimeter is 36 cm. Let's substitute these values into the formula and solve for the length.

36 = 2 * (Length + 8)

To solve for the length, we can start by simplifying the equation:

36 = 2 * Length + 16

Next, we can isolate the term with the length:

2 * Length = 36 - 16

2 * Length = 20

Finally, we can solve for the length by dividing both sides of the equation by 2:

Length = 20 / 2

Length = 10

Therefore, the length of the rectangle is 10 cm.

Answer:

The length of the rectangle is 10 cm.
