It seems the image you intended to share is missing. To help you solve the problem, could you please:

  1. Re-upload the image, or
  2. Describe the problem in detail (e.g., the shape of the figure, dimensions given, what needs to be calculated like area, perimeter, etc.)?

Once you provide this information, I can assist you with the solution.

Example of a detailed description (if it's a common problem):
"If it's a circle with radius 5 cm inscribed in a square, find the area of the shaded region (the square minus the circle)."

Let me know!
