1. Let’s translate the perimeter of the triangle into cm:
8 dm 6 cm = 86 cm.
2. Find the sum of two identical sides of a triangle:
3 dm * 2 = 6 dm = 60 cm.
3. Subtract the sum of its two sides from the perimeter of the triangle, we get the length of the third side:
86 cm – 60 cm = 26 cm.
Answer: The length of the third side of the triangle is 23 cm.
