Question

Знайдіть периметр трикутника, якщо його середні лінії дорівнюють 5 см, 6 см, 9 см *

Answer 1

Ответ:

Р=(5+6+9)×2= 40см так як середні лінії в двічі менші за сторони

Answer 2

Finding the Perimeter of a Triangle with Given Medians

To find the perimeter of a triangle when the lengths of its medians are given, we can use the fact that the medians of a triangle divide each other in a 2:1 ratio. Let's denote the lengths of the medians as m1, m2, and m3.

The formula to find the perimeter of a triangle using the lengths of its medians is:

Perimeter = 3 * (m1 + m2 + m3) / 2

Now, let's substitute the given lengths of the medians into the formula:

Perimeter = 3 * (5 + 6 + 9) / 2

Calculating this expression, we get:

Perimeter = 3 * 20 / 2 = 30

Therefore, the perimeter of the triangle is 30 cm.
