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 perimeter of the triangle.

In order to find the perimeter of a triangle, we will start by remembering what the perimeter is and how to find it.

So, the perimeter of any geometric figure is the sum of the lengths of all its sides. For a triangle, the perimeter can be written in the form of the formula:

P = a + b + c;

We know the length of one of the sides is 83.6 cm, and we also know that the length of the second side is 14.8 cm longer than the first, and the third is 8.6 cm longer than the second.

We are looking for the length of the second:

83.6 + 14.8 = 98.4 cm;

The third side:

98.4 + 8.6 = 107 cm.

P = 83.6 + 98.4 + 107 = 289 cm.
