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.
1. As you know, the perimeter of a triangle P is equal to the sum of its three dimensions.
2. By the condition of the problem, the second side is 14.8 cm longer than the first, which is 83.6 cm.
We calculate the length by adding two quantities.
83.6 + 14.8 = 98.4 cm.
3. Since the third side is 8.6 cm longer than the second, we get its value if we add 8.6 cm to the obtained length.
98.4 cm + 8.6 cm = 107 cm.
4. Finally, we find out the perimeter of the triangle.
P = 83.6 cm + 98.4 cm + 107 cm = 289 cm.
Answer: The perimeter is 289 centimeters.
