Answer:

[tex]12x^2+4x[/tex]

Step-by-step explanation:

The area of a square or rectangle can be found by multiplying the width by the height. Since we now both, we can create an expression.

[tex](3x+1)*(4x)[/tex]

Now we can apply the distributive law/property to expand the expression.

[tex]3x(4x)+1(4x)[/tex]

Finally, we can simplify.

[tex]12x^2+4x[/tex]
