Answer :

To find the perimeter of a triangle, you need to sum the lengths of its three sides. The perimeter is the total distance around the triangle.

Here, we are given the side lengths of the triangle:
- The first side length is 11 inches.
- The second side length is 5 inches.
- The third side length is 1 inch.

To calculate the perimeter, you simply add these three side lengths together:

[tex]\[ \text{Perimeter} = 11 \text{ inches} + 5 \text{ inches} + 1 \text{ inch} \][/tex]

Now, let's add them step-by-step:

1. Add the first two sides:
[tex]\[ 11 \text{ inches} + 5 \text{ inches} = 16 \text{ inches} \][/tex]

2. Add the result to the third side:
[tex]\[ 16 \text{ inches} + 1 \text{ inch} = 17 \text{ inches} \][/tex]

Thus, the perimeter of the triangle is 17 inches.
