The equation you provided, $2l + 2w = p$, appears to represent the formula for the perimeter $p$ of a rectangle, where $l$ is the length and $w$ is the width.

To solve for any one variable, you need values for the others. For example:

1. Solving for $l$ (length): $2l + 2w = p \quad \Rightarrow \quad 2l = p - 2w \quad \Rightarrow \quad l = \frac{p - 2w}{2}$

2. Solving for $w$ (width): $2l + 2w = p \quad \Rightarrow \quad 2w = p - 2l \quad \Rightarrow \quad w = \frac{p - 2l}{2}$

If you provide values for either $p$, $l$, or $w$, I can solve for the unknowns.

Would you like more details or have any questions?

Here are 5 related questions:

1. What is the perimeter if $l = 5$ and $w = 3$?
2. Can you rearrange the formula for $w$ if the perimeter is given as 24?
3. How would you express $l$ if the perimeter is known to be 30?
4. How does the perimeter change if both $l$ and $w$ are doubled?
5. How can you graph the relationship between $l$ and $w$ for a constant perimeter?

Tip: Remember that in geometry, solving for one variable often requires isolating it on one side of the equation while performing inverse operations on the other side.
