Question

Какой периметр у треугольника если первая сторона 18см,вторая в 3 раза меньше,а длина третьей стороны 14см?

Answer 1

Периметр треугольника -это сумма всех его сторон
1-я сторона =18
2-я сторона=18/3=6
3-я стороная 14
Периметр=18+6+14=38см

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, we have the following information:

- The length of the first side is 18 cm. - The second side is 3 times smaller than the first side. - The length of the third side is 14 cm.

Let's calculate the perimeter step by step:

1. Find the length of the second side: - The second side is 3 times smaller than the first side, so it would be 18 cm / 3 = 6 cm.

2. Add up the lengths of all three sides: - The first side is 18 cm. - The second side is 6 cm. - The third side is 14 cm. - Therefore, the perimeter of the triangle is 18 cm + 6 cm + 14 cm = 38 cm.

So, the perimeter of the triangle is 38 cm.
