One side of the triangle is 16 centimeters, the second is 2 decimeters more than the first, and the third is 2 times less than the sum of 1 and 2 sides. Find the perimeter of the triangle.

1 decimeter = 10 cm, so the second side is 16 + 2 * 10 = 36 cm
The third side is (16 + 36) / 2 = 26 cm
Perimeter is the sum of the lengths of all sides, then:
P = 36 + 16 + 26 = 78 cm
Answer: 78 cm
