Answer:Area of rectangle, .

Step-by-step explanation:We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.

The area of a rectangle is equal to the product of its length and breadth. It is given by :

Let us consider, L = (2x-4) units and B = (x+1) units

Plugging the side lengths in above formula:

So, the function that models the area of a rectangle is .
