Answer:

C. 1.5w^2 + 7.5w + 9

Step-by-step explanation:

Without frame:

The width is w. The height is 1.5w.

With frame:

The width is w + 1.5 + 1.5 = w + 3

The height is 1.5w + 1.5 + 1.5 = 1.5w + 3

The area of the framed portrait is height * width

area = (1.5w + 3)(w + 3)

area = 1.5w^2 + 4.5w + 3w + 9

area = 1.5w^2 + 7.5w + 9
