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

1) What is the second side of the triangle?
83.6 + 14.8 = 98.4 cm.
2) How long is the third side of the triangle?
98.4 + 8.6 = 107 cm.
3) What is the perimeter of the triangle?
To find the perimeter of a triangle, add the lengths of its three sides.
83.6 + 98.4 + 107 = 289 cm.
Answer: the perimeter of the triangle is 289 cm.
