| **Find the perimeter of the triangle if one side of the triangle is 29 cm, the other is 5 cm shorter, and the third is 3 cm shorter than the other.**

A triangle is a geometric figure formed by three points that do not lie on one straight line and segments connecting these points in pairs. The perimeter of a triangle is equal to the sum of the lengths of its three sides.

1). Determine what the length of the second side of the triangle is equal to.

29 – 5 = 24 centimeters.

2). Let’s calculate the length of the third side of the triangle.

24 – 3 = 21 centimeters.

Let’s answer the question of the problem.

3). Find the perimeter of the triangle.

29 + 24 + 21 = 74 centimeters.

Answer: The perimeter of a triangle is seventy-four centimeters.
