Урок 3 длина прямо уг. 17,2 а ширина в 4 раза меньше найдите пиримитер прямугольника. 40 см 42 см 41 см 43 см

Answer 1

Ответ:

Пошаговое объяснение:

17,2 : 4 = 4,3 см

P = 2(a + b)

Р = 2 (17,2 + 4,3) = 2 * 21,5 = 43 см

Ответ 43 см

Answer 2

Ответ:

Пошаговое объяснение:

1) 17,2 : 4 = 4,3 (см) - ширина

2) 2 * (17,2 + 4,3) = 2 * 21,5 = 43 (см) - периметр прямоугольника

Answer 3

Problem Analysis

To find the perimeter of a rectangle, we need to know the length and width of the rectangle. In this case, we are given that the length of the rectangle is 17.2 units and the width is 4 times smaller than the length. We need to calculate the perimeter of the rectangle.

Calculation

Let's start by finding the width of the rectangle. We know that the width is 4 times smaller than the length, so we can calculate it by dividing the length by 4.

Width = Length / 4

Substituting the given length value:

Width = 17.2 / 4

Now, we can calculate the perimeter of the rectangle using the formula:

Perimeter = 2 * (Length + Width)

Substituting the given length and calculated width values:

Perimeter = 2 * (17.2 + (17.2 / 4))

Now, let's calculate the perimeter using the given values.

Calculation Results

The perimeter of the rectangle with a length of 17.2 units and a width 4 times smaller than the length is 72.4 units.

Conclusion

The perimeter of the rectangle is 72.4 units.
