The image appears to depict a rectangular shape with labeled dimensions. The vertical side of the rectangle is labeled $x + 3$, and the horizontal side is labeled $x + 3$ as well. Additionally, there is a numerical value of $7$ nearby.

To assist you better, could you clarify the exact problem or task you would like solved? For example:

1. Are you looking for the area of the rectangle?
2. Do you need the perimeter of the rectangle?
3. Does the number $7$ relate to the rectangle (e.g., is it the area or perimeter)?
4. Should I simplify an expression involving these dimensions?
5. Or, would you like a full exploration of this diagram's mathematical properties?

Let me know how you'd like to proceed! Here's a quick tip: if the problem involves expressions, always double-check whether $x$ is defined or if you're solving for it.
