The answer to your question is the letter B. 20x² - 4x - 16

Explanation:

Data

length = 5x + 4

width = 4x - 4

Formula

Area of a rectangle = length x width

Substitution

Area of a rectangle = (5x + 4)(4x - 4)

Expand

Area of a rectangle = 20x² - 20x + 16x - 16

Simplify like terms

Area of a rectangle = 20x² - 4x - 16
