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
To find the perimeter of an octagon, multiply the length of one side by 8 (the number of sides) Since the side is 6 inches long, the perimeter is 48 in, because 6 x 8 = 48
