The length of the first side of the triangle is 34 cm, the second is 29 cm, and the length of the third is 30 cm less than the sum of the lengths of the first two sides. 1 Find out the length of the third side of the triangle. 2 Calculate the perimeter of the triangle.

Determine how many centimeters the sum of the lengths of the first and second sides of a given triangle corresponds to:

34 + 29 = 63.

Let us determine how many centimeters the length of the third side of a given triangle corresponds to, knowing by the condition of the problem that the sum of the lengths of the first and second sides exceeds it by thirty centimeters:

63 – 30 = 33.

Determine how many centimeters the perimeter of this triangle corresponds to:

33 + 63 = 96.

Answer: The length of the third side is 33 centimeters, and the perimeter is 96.
