The expression [tex]$w(2w - 4)$[/tex] represents the area of a rectangle given the width, [tex][tex]$w$[/tex][/tex]. What does [tex]$2w - 4$[/tex] represent in the expression?

A. The length of the rectangle
B. The perimeter of the rectangle
C. The length of the diagonal of the rectangle
D. The difference between the length and the width



Answer :

Let's analyze the given expression [tex]\( w(2w - 4) \)[/tex] which represents the area of a rectangle.

1. Understanding the components of the expression:
- Recall that the area of a rectangle is calculated as [tex]\( \text{Width} \times \text{Length} \)[/tex].
- Here, the expression for the area is given as [tex]\( w(2w - 4) \)[/tex].

2. Identifying the width:
- The variable [tex]\( w \)[/tex], which is the multiplier outside the parentheses, represents the width of the rectangle.

3. Finding the length:
- To find out what [tex]\( 2w - 4 \)[/tex] represents, we need to compare this expression with the standard area formula of a rectangle [tex]\( \text{Width} \times \text{Length} \)[/tex].
- Since [tex]\( w \)[/tex] is the width and the entire expression [tex]\( w(2w - 4) \)[/tex] represents the area, the term within the parentheses [tex]\( 2w - 4 \)[/tex] must represent the length of the rectangle.

Therefore, based on our analysis, the term [tex]\( 2w - 4 \)[/tex] represents the length of the rectangle.
