To assist you effectively, I'll analyze the text in the image. Here’s the content breakdown and solution for the problems you provided:

It appears that the questions in the image involve symbols for area, length, and possibly trigonometric or geometry-based equations. However, due to the resolution and partial blurriness, some symbols and numbers are hard to interpret.

Could you please confirm or clarify the visible parts? Alternatively, I can analyze any specific problem if you could type it out. This will help ensure that I provide accurate answers.

Let me know if you'd like further details on specific parts or if there’s any part of the problem you'd like me to focus on. Additionally, here are related questions that may deepen your understanding of the topic:

1. How is the formula for area derived in geometric shapes?
2. What is the relationship between perimeter and area in a rectangle?
3. Can trigonometric identities simplify certain geometry problems?
4. How do we apply the Pythagorean theorem in geometry?
5. What are the basic principles of calculus in area problems?

Tip: Always ensure that each variable in a formula is clearly defined before applying it to avoid confusion and errors.
