A square painting is surrounded by a frame. the outside edges of the frame are x inches in length, and the frame is 3 inches thick. What is the total area of the frame?
A)-12x+36 B)12x-36 C)x^2+12x+36 D)x^2-12x-36 Is it C or D?
I believe the correct answer from the choices listed above is the third option. The total area of the frame would be expressed as A = x^2+12x+36. Hope this answers the question. Have a nice day.
