Answer:
perimeter = 48 in
Explanation:
The perimeter of the shape is the sum of its side lengths.
We are given that the shape is a regular octagon. This means that it has eight equal sides.
Therefore:
perimeter of regular octagon = 8 * side length
Since the side length is given = 6 in, therefore:
perimeter = 8 * 6 = 48 in
Hope this helps :)
