In triangle ABC, the length of side AB is 5 centimeters, side BC is 8 cm longer than side AB B

In triangle ABC, the length of side AB is 5 centimeters, side BC is 8 cm longer than side AB B, and the length of side AC and less than the sum of the lengths of sides A B and C by 6 centimeters Find the perimeter of the triangle.

1. Let’s calculate the length of the side BC.

BC = 5 + 8 = 13 (cm).

2. Let’s calculate the sum of the lengths of the sides AB and BC.

5 + 13 = 18 (cm).

3. Let’s calculate the length of the side AC.

AC = 18 – 6 = 12 (cm).

4. Calculate the perimeter of the triangle.

P = AB + BC + AC.

P = 5 + 13 + 12 = 30 (cm).

Answer: The perimeter of the triangle is 30 cm.
