    Begin with the formula for the area of a rectangle:

    Area of rectangle = length times width

    6x² - 5x - 4 = length * (2x + 1) ← substituted known expressions

    (3x - 4) (2x + 1) = length * (2x + 1) ← factored the trinomial

    3x - 4 = length ← divided both sides of the equation by (2x + 1)

    Answer: Length of the rectangle is 3x - 4
