One side of the triangle is 83.6 cm, the second is 14.8 cm longer than the first, and the third is 8.6 cm longer than the second. Find the pyremeter of the triangle.

1. According to the specification, the length of the first side of the triangle is 83.6 cm.

2. Calculate what is the length of the second side of this triangle, if we know that it is 14.8 cm longer than the first side.

83.6 + 14.8 = 98.4 cm.

3. Now let’s determine the length of the third side, which is 8.6 cm longer than the second side.

98.4 + 8.6 = 107 cm.

4. Knowing the length of all three sides of the triangle, we determine what its perimeter is equal to by adding the lengths of all its sides.

83.6 + 98.4 + 107 = 289 cm.

Answer: The perimeter is 289 cm.
