Calculate the perimeter of an equilateral triangle if the length of its side is 25 millimeters. How many times the perimeter of the triangle increases if the length of its side is increased by 3 times.

Let’s solve the task of actions with explanations.
1) 25 * 3 = 75 millimeters – the perimeter of an equilateral triangle with a side length of 25 millimeters;
2) 25 * 3 = 75 millimeters – the length of the side of an equilateral triangle, if it is increased three times, since its length was equal to 25 millimeters;
3) 75 * 3 = 225 millimeters – the perimeter of an equilateral triangle with a side length of 75 millimeters;
4) 225: 75 = 3 times – this is how much the perimeter of the triangle increases if the length of its side is increased by 3 times.
Answer: 3 times.
