It seems that the document you uploaded contains a math worksheet in Arabic. Based on the visible content, there are questions on solving systems of equations involving linear and quadratic equations as well as geometry problems involving a rectangular garden's dimensions.

Here is a breakdown of the relevant information:

1. First Question: Solve systems of equations (linear and quadratic equations).
2. Second Question: Geometry problem related to a rectangular garden where the diagonal is $84 \, m$ and the perimeter is $30 \, m$.

Would you like help solving any of these problems, or do you want a deeper analysis of the system of equations?

Here are 5 related questions that expand on these topics:

1. How do you solve a system of a linear and a quadratic equation?
2. Can you derive the formula for the diagonal of a rectangle using Pythagoras' theorem?
3. What methods can be used to solve quadratic equations?
4. How do you calculate the area of a rectangle given the diagonal and the perimeter?
5. What are the different methods to solve systems of equations (e.g., substitution or elimination)?

Tip: When solving systems of equations, substitution is often useful when one of the equations is already solved for a single variable.
