Question

Провалку длиной 15 сантиметров согнули Так что получился равносторонний треугольник Чему равен периметр этого треугольника? Чему равна его сторона?

Answer 1

1) надо 15 ÷ 3 так мы узнаем длину 1 стороны -5. 2) (5+5)×2=20(см)периметр Ответ : 20 см длина периметра

Answer 2

15/3 равно 5 см(это каждая сторона равностороннего треугольника)
периметр его равен 20 см (5+5*2)

Answer 3

Perimeter of an Equilateral Triangle

To find the perimeter of an equilateral triangle, we need to know the length of one side of the triangle. In this case, the given information is that a 15-centimeter-long wire was bent to form an equilateral triangle. We can use this information to calculate the perimeter and the length of each side of the triangle.

Calculating the Perimeter

Since an equilateral triangle has all three sides equal in length, we can calculate the perimeter by multiplying the length of one side by 3. Therefore, the perimeter of the equilateral triangle formed by bending a 15-centimeter-long wire is:

Perimeter = 15 cm * 3 = 45 cm.

So, the perimeter of the equilateral triangle is 45 centimeters.

Calculating the Length of Each Side

To find the length of each side of the equilateral triangle, we can divide the perimeter by 3. Therefore, the length of each side of the equilateral triangle is:

Length of each side = 45 cm / 3 = 15 cm.

So, each side of the equilateral triangle is 15 centimeters long.

Therefore, the perimeter of the equilateral triangle is 45 centimeters, and each side of the triangle is 15 centimeters long.
