| **The side of the triangle is 6.3 cm, 20.8 cm less than the second side and 0.9 cm more than the third side. Find the perimeter of the triangle.**

To solve this problem, remember that the perimeter of a triangle is equal to the sum of the lengths of all its sides. Let’s calculate what is the first side of the triangle.

6.3 + 20.8 = 27.1 centimeters.

Let’s calculate the length of the third side.

6.3 – 0.9 = 5.4 centimeters.

Let’s calculate what the perimeter is.

P = 27.1 + 5.4 + 6.3 = 38.8 centimeters.

Answer: 38.8 centimeters.
