The length of a side of a rectangle is 2 units less than a number, and the width is 4 units more than the length. which of the following expressions represents the area of the rectangle, in square units?

The correct answer is option C.  x² - 4

Step-by-step explanation:

Area of rectangle  = Length * Width

It is given that ,

The length of a side of a rectangle is 2 units less than a number, and the width is 4 units more than the length.

Let 'x' be the number

Length of rectangle = x - 2

Width = Length + 4 = x - 2 + 4 = x + 2

To find the area of rectangle

Area = Length *  Width

Area = (x - 2)*(x + 2) = x² - 4

Therefore option C.  x² - 4 is the correct answer
