Question

Дві сторони рівнобедреного трикутника дорівнюють 98 см і 28 см. Знайдіть периметр трикутника. (Відповідь записати без одиниць вимірювання)​

Answer 1

Ответ:

224

Объяснение:

Так как у треугольника сумма двух сторон больше третей, то третья сторона равна 98 см.

(28+28<98)

Тогда периметр 98+98+28=224.

Answer 2

Perimeter of an Isosceles Triangle

To find the perimeter of an isosceles triangle, we need to know the lengths of the two equal sides. In this case, the two sides of the triangle are given as 98 cm and 28 cm.

The perimeter of a triangle is calculated by adding the lengths of all three sides. Since the given triangle is isosceles, we can assume that the third side is also equal to the other two sides.

Therefore, the perimeter of the triangle can be calculated as follows:

Perimeter = Length of Side 1 + Length of Side 2 + Length of Side 3

Since the two equal sides are given as 98 cm and 28 cm, we can substitute these values into the formula:

Perimeter = 98 cm + 28 cm + 98 cm

Simplifying the equation, we get:

Perimeter = 224 cm

Therefore, the perimeter of the given isosceles triangle is 224 cm.
