Question

Найди длину третьей стороны треугольника если его периметр равен 12 сантиметра а длина других сторон 2 сантиметра и 4 самых Запиши решения составленная рождения

Answer 1

Периметр Р = а + в + с, с = Р - а - в

12 - (3 + 4) = 12 - 7 = 5 см

Ответ. 5 см. 

Answer 2

Calculating the Length of the Third Side of a Triangle

To find the length of the third side of a triangle when its perimeter is 12 centimeters and the lengths of the other two sides are 2 and 4 centimeters, we can use the formula for the perimeter of a triangle:

Perimeter of a Triangle = Sum of all Three Sides

Given: - Length of one side = 2 centimeters - Length of another side = 4 centimeters - Perimeter = 12 centimeters

We can use the formula to find the length of the third side: Third side length = Perimeter - (Length of first side + Length of second side)

Substitute the given values: Third side length = 12 - (2 + 4)

Calculating: Third side length = 12 - 6 = 6

Therefore, the length of the third side of the triangle is 6 centimeters.
