Question

Каждая сторона треугольника ровна 6 см надо найти его периметр.как изменится периметр треугольника, если каждую сторону увеличить на 3 см?

Answer 1

Периметр треугольника 3*6=18см
при увеличении каждой стороны на 3 см периметр вырастет на 3*3=9см

Answer 2

Finding the 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, each side of the triangle is given as 6 cm. Therefore, the initial perimeter of the triangle is:

Perimeter = 6 cm + 6 cm + 6 cm = 18 cm.

Increasing the Length of Each Side

Now, let's consider what happens when we increase the length of each side by 3 cm.

To calculate the new perimeter, we need to add the increased length to each side of the triangle. Since each side is increased by 3 cm, the new length of each side is 6 cm + 3 cm = 9 cm.

Therefore, the new perimeter of the triangle is:

New Perimeter = 9 cm + 9 cm + 9 cm = 27 cm.

Conclusion

In summary, the initial perimeter of the triangle with each side measuring 6 cm is 18 cm. When we increase the length of each side by 3 cm, the new perimeter becomes 27 cm.
