Answer:
Width = x² + 5x - 4
Explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,
![(4x^2+20x-16)/(4)=\frac{4(\text{Width})}{4}](https://img.qammunity.org/2022/formulas/mathematics/college/5a5nj8mud7kt1jirefseg23ptz0ljxjoeg.png)
x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
