1. According to the data presented in the problem statement, the perimeter of the triangle is 24 cm.
2. Let’s calculate what is the length of the base, if we know that its length is 25% of the perimeter of the triangle.
24/100 * 25 = 6 cm.
3. Now let’s calculate what is the sum of the lengths of the other two sides of this triangle.
24 – 6 = 18 cm.
4. Next, we find the length of the lateral side, if the condition of the problem says that the triangle is isosceles.
18/2 = 9 cm.
Answer: The length of the side of the triangle is 9 cm.
