In the KMN triangle, the MN side is 76cm, the KN side is 34cm longer than MN, and the KM side is 21cm longer than MN. Find the perimeter of the triangle.

Determine the length of the side МN of the triangle.
MN = KN + 34 = 76 + 34 = 110 cm.
Let us determine the length of the CM side.
KM = MN + 21 cm = 76 + 21 = 97 cm.
Determine the perimeter of the triangle KMN.
Рkmn = KN + MN + KM = 76 + 110 +97 = 283 cm.
Answer: The perimeter of the triangle is 181 cm.
