Answer:

The area of the entire rectangle is  [tex]7x^2-4x[/tex].

Step-by-step explanation:

Given : A rectangle has a height of x and a width of 7x – 4.

To find : Express the area of the entire rectangle ?

Solution :

The height of the rectangle l=x.

The width of the rectangle b=7x-4.

The area of the rectangle is

[tex]\text{Area}=l\times b[/tex]

[tex]\text{Area}=x\times (7x-4)[/tex]

[tex]\text{Area}=7x^2-4x[/tex]

Therefore, the area of the entire rectangle is  [tex]7x^2-4x[/tex].
