| 1) We find out the length of the third side of the triangle, knowing how much longer it is than the first and second sides, which are equal to 6 centimeters.

6 + 8 = 14.

The third side of the triangle is 14 centimeters.

2) Now let’s calculate what its perimeter is. It is known that the perimeter of any figure is equal to the sum of the lengths of its sides, so we just add up the data we know about the three sides of the triangle (two sides are 6 centimeters and one is 14).

6 + 6 + 14 = 12 + 14 = 26.

The perimeter of the triangle is 26 centimeters.

Answer: 26 centimeters.
