Respuesta :

From the question it is given that the length of the rectangle is 4 less than the three time of the width.

[tex]l=3w-4[/tex]

Here, 'l' represnts the length and 'w' represents the width.

The area of the rectangle is,

[tex]A=l\times w[/tex]

Substitute expression 'l=3w-4' in the above equation.

[tex]\begin{gathered} A=(3w-4)w \\ A=3w^2-4w \end{gathered}[/tex]

Thus, the correct option is option D.
