The equation that can be ued to solve for the width of the rectangular frame is 2x² + 14x - 40 = 0.

<h3>What is the equation that can be used to solve for the width?</h3>

A rectangle is a 2-dimensional quadrilateral with four right angles.

Area of a rectangle = length x width

(2x + 4) x (2x + 10) = 120

Expand the brackets

4x² + 20x + 8x + 40 = 120

Add similar terms

4x² +28x + 40 = 120

4x² +28x - 80 = 0

Divide through by 2

2x² + 14x - 40 = 0
