What is the perimeter? If necessary, round to the nearest tenth kilometers

To calculate the perimeter of a shape, you need to add up the lengths of all its sides. If you have a specific shape in mind, please provide the lengths of its sides or the type of shape (like a rectangle, triangle, etc.), and I can help you with the calculation.

If the perimeter is provided in kilometers, remember to round your final answer to the nearest tenth as needed. Please provide the details for further assistance!
