The perimeter of a polygon is defined as the sum of all of its sides lengths. We are given the side lengths, so we can add them up to find the perimeter of the polygon.
Perimeter = 5.5 + 4.59 + 2.21 + 6 + 2.9
Perimeter = 21.2 ft.
Thus, the perimeter of the polygon which is a pentagon as it has 5 sides will be 21.2 ft.
