The length of the first side of the triangle is 18 cm, the second is 3 times less

The length of the first side of the triangle is 18 cm, the second is 3 times less, and the length of the third side is 14 cm. Find the perimeter of this triangle.

Let’s solve this task by actions with explanations:
1) 18: 3 = 6 centimeters – the length of the second side of the triangle, since the length of the second side is 3 times less than the length of the first side, 18 centimeters;
2) 18 + 6 + 14 = 24 + 14 = 38 centimeters – the perimeter of this triangle with sides of 18 centimeters, 6 centimeters and 14 centimeters.
Answer: 38 centimeters.
