1. The problem is to find the perimeter of a shape. 2. The perimeter of a polygon is the sum of the lengths of all its sides. 3. The formula for the perimeter $P$ of a polygon with side lengths $s_1, s_2, \ldots, s_n$ is: $$P = s_1 + s_2 + \cdots + s_n$$ 4. To solve, add all the side lengths together. 5. For example, if the polygon is a rectangle with length $l$ and width $w$, the perimeter is: $$P = 2l + 2w$$ 6. If you provide the side lengths or shape type, I can calculate the exact perimeter.
