The variable expression that describes the length $l$ will be:
$l = 4 x$

#### Explanation:

Given: The length of a rectangle is four times the width.

The width is represented by x​.

Let the length be represented by $l$.

Then the variable expression that describes the length $l$ will be:

$l = 4 \times x$

Or

$l = 4 x$
