Hi there! :)
[tex]\huge\boxed{2x}[/tex]
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.
