Hi there! :)

$\huge\boxed{2x}$

Recall that the formula of a rectangle is A = l × w

We are asked to solve for the width, so rewrite the equation:

A / l = w

8x² / 4x = w

When dividing, divide the coefficients then divide the variables.

8 / 4 = 2

x² / x = x

Therefore, 8x² / 4x = 2x. The width of the rectangle is 2x units.
