Question

Перриметр равностороннего треугольника 24см.найти перриметр квадрата сторона которого на 3см.больше стороны треугольника

Answer 1

Пусть х (см)- сторона треугольника, тогда х+3 (см) - сторона квадрата
(х+х+х) =3 * х = 24 см - периметр треугольника
х= 24 : 3 = 8 см - сторона треугольника
х+3 = 8+3 = 11 см - сторона квадрата
4 * 11 = 44 см - периметр квадрата (сумма всех сторон)
Ответ: 44 см

Answer 2

Perimeter of an Equilateral Triangle

To find the perimeter of an equilateral triangle, we need to know the length of one side. Let's assume the length of each side of the equilateral triangle is x.

The formula to calculate the perimeter of an equilateral triangle is:

Perimeter = 3 * side length

In this case, the perimeter of the equilateral triangle is given as 24 cm. So we can set up the equation:

24 = 3 * x

To find the value of x, we can divide both sides of the equation by 3:

x = 24 / 3 = 8 cm

Therefore, each side of the equilateral triangle measures 8 cm.

Perimeter of a Square

Now, let's find the perimeter of a square whose side length is 3 cm longer than the side length of the equilateral triangle.

The side length of the square is given as x + 3 cm.

The formula to calculate the perimeter of a square is:

Perimeter = 4 * side length

Substituting the value of the side length of the square, we have:

Perimeter = 4 * (x + 3)

To find the perimeter, we need to substitute the value of x we found earlier:

Perimeter = 4 * (8 + 3) = 4 * 11 = 44 cm

Therefore, the perimeter of the square is 44 cm.

Summary:

- The perimeter of the equilateral triangle is 24 cm, with each side measuring 8 cm. - The perimeter of the square, whose side length is 3 cm longer than the side length of the equilateral triangle, is 44 cm.
