Answer:


12x^2+4x

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.


(3x+1)*(4x)

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


3x(4x)+1(4x)

Finally, we can simplify.


12x^2+4x
