    The correct answer is A. 1.5w² + 5w + 4

    Step-by-step explanation:

    1. Let's review the information given to us to answer the question correctly:

    Height of the portrait = 1.5 times its width in inches

    Frame = 2 inches all along its perimeter

    2. What is an expression for the area of the framed portrait in terms of w?

    Let's recall that the area of a rectangle is length or height * width.

    A = height * width

    Now, we can replace in terms of w:

    A = 1.5w * w

    But we need to add the 2 inches of the frame, this way:

    A = (1.5w + 2) * (w + 2)

    A = 1.5w² + 2w + 3w + 4

    A = 1.5w² + 5w + 4

    The correct answer is A. 1.5w² + 5w + 4
