Question

Найди периметр треугольника если длина первой его стороны 17 см, второй - 23 см, а третьей 1 1 см. какие данные в задаче нужно изменить так,чтобы в ответе получилось 40? попробуй найти разные способы .

Answer 1

17+13+10 = 40
7+23+10=40
17+13+10=40
где-то так

Answer 2

Perimeter of a Triangle

To find the perimeter of a triangle, you need to add up the lengths of all three sides. In this case, the lengths of the sides are given as follows:

- Side 1: 17 cm - Side 2: 23 cm - Side 3: 11 cm

To calculate the perimeter, you simply add up these lengths:

Perimeter = Side 1 + Side 2 + Side 3

Perimeter = 17 cm + 23 cm + 11 cm

Perimeter = 51 cm

So, the perimeter of the triangle is 51 cm.

Changing the Data to Get a Perimeter of 40

To obtain a perimeter of 40, we need to change the lengths of the sides. Let's explore a few different possibilities:

Option 1: Changing Side 1 to 10 cm - Side 1: 10 cm - Side 2: 23 cm - Side 3: 11 cm

Perimeter = Side 1 + Side 2 + Side 3

Perimeter = 10 cm + 23 cm + 11 cm

Perimeter = 44 cm

In this case, the perimeter is not equal to 40.

Option 2: Changing Side 2 to 17 cm - Side 1: 17 cm - Side 2: 17 cm - Side 3: 11 cm

Perimeter = Side 1 + Side 2 + Side 3

Perimeter = 17 cm + 17 cm + 11 cm

Perimeter = 45 cm

Again, the perimeter is not equal to 40.

Option 3: Changing Side 3 to 12 cm - Side 1: 17 cm - Side 2: 23 cm - Side 3: 12 cm

Perimeter = Side 1 + Side 2 + Side 3

Perimeter = 17 cm + 23 cm + 12 cm

Perimeter = 52 cm

Once again, the perimeter is not equal to 40.

Based on these calculations, it is not possible to obtain a perimeter of 40 by changing the lengths of the sides in this particular triangle.
