  • 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]
