If the sides of the triangle are a, b and c, then the perimeter of the triangle P is calculated by the formula:
P = a + b + c.
By the condition of the problem, we have: sides a = 25 cm, b = 83 cm and perimeter P = 182 cm.
Hence,
c = P – a – b = 182 cm – 25 cm – 83 cm = 74 cm.
Answer: the third side of the triangle is 74 cm.
