Final answer:
The expression that represents the area of the rectangle is (2x + 1)(5x - 4).
Step-by-step explanation:
The area of a rectangle can be found by multiplying its length and width.
In this case, the width is 2x + 1 and the length is 5x - 4.
So, the expression that represents the area of the rectangle is (2x + 1)(5x - 4).
