Find the perimeter of the triangle. Round to the nearest tenth if necessary.

The side lengths are:
- 10.8
- 18.2
- 13

Options:
A) 66.9
B) 58
C) 49.6
D) 49.9

Answer :

To find the perimeter of a triangle, you need to add up the lengths of all its sides. In this case, the side lengths given are 10.8, 18.2, and 13.

Let's calculate the perimeter step-by-step:

  1. Start by adding the first two sides:
    [tex]10.8 + 18.2 = 29.0[/tex]

  2. Next, add the third side to this sum:
    [tex]29.0 + 13 = 42.0[/tex]

So, the perimeter of the triangle is 42.0.

Since the solution to the perimeter calculation is 42.0 and is not included among the given multiple choice options, there is likely an error in the provided options. However, based strictly on the calculation, the correct answer is 42.0.
