The sides of the triangle are 2 cm 5 cm 6 cm. Find the larger side of a similar triangle, the remitter of which is 26 cm.

1. Find the aspect ratio in the first triangle:
2: 5: 6.
2. Find the sum of all sides in parts, which corresponds to the perimeter of a similar triangle:
2 + 5 + 6 = 13 pieces.
3. Divide the perimeter into 13 parts, we get the length of one part:
26/13 = 2 cm.
4. Find the largest side of the triangle by multiplying the largest part of the sides by 2 cm:
2 * 6 = 12 cm.
Answer: The large side of the triangle is 12 cm.
