Question

Ширина прямоугольника 3см.длина5см.Начерти отрезок в 4 раза короче периметра прямоугольника.

Answer 1

Периметр=3+5+3+5=16 см
16/4=4см должен быть отрезок

Answer 2

(3+5)*2= 16(см)- периметр прямоугольника
16:4=4(см)- отрезок который надо начертить
Ответ: отрезок должен быть 4 см

Answer 3

Problem Analysis

We are given the width and length of a rectangle, and we need to draw a line that is 4 times shorter than the perimeter of the rectangle.

Solution

To find the perimeter of the rectangle, we can use the formula: perimeter = 2 * (width + length).

Let's calculate the perimeter of the rectangle using the given width and length: - Width = 3 cm - Length = 5 cm

Perimeter = 2 * (3 + 5) = 2 * 8 = 16 cm.

Now, we need to draw a line that is 4 times shorter than the perimeter of the rectangle. To find the length of this line, we can divide the perimeter by 4:

Length of the line = Perimeter / 4 = 16 cm / 4 = 4 cm.

Therefore, the length of the line that is 4 times shorter than the perimeter of the rectangle is 4 cm.

Conclusion

To draw a line that is 4 times shorter than the perimeter of a rectangle with a width of 3 cm and a length of 5 cm, the length of the line should be 4 cm.
