Question

ОДНА СТОРОНА ТРЕУГОЛЬНИКА РАВНА 28 СМ, ВТОРАЯ НА 8 СМ МЕНЬШЕ ПЕРВОЙ , А ТРЕТЬЯ НА 2 СМ МЕНЬШЕ ВТОРОЙ ,НАЙДИТЕ ПЕРИМЕТР ТРЕУГОЛЬНИИКА

Answer 1

Одна сторона= 28
вторая сторона=20
третья сторона=18
28+20+18=66

Answer 2

Perimeter of a Triangle

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

- The length of one side is 28 cm. - The length of the second side is 8 cm less than the first side. - The length of the third side is 2 cm less than the second side.

Let's calculate the perimeter step by step.

1. Find the length of the second side: - The second side is 8 cm less than the first side, so it is 28 cm - 8 cm = 20 cm.

2. Find the length of the third side: - The third side is 2 cm less than the second side, so it is 20 cm - 2 cm = 18 cm.

3. Calculate the perimeter: - Add up the lengths of all three sides: 28 cm + 20 cm + 18 cm = 66 cm.

Therefore, the perimeter of the triangle is 66 cm.
