Question 861678: A square painting is surrounded by a frame. The outside edges of the frame are (3x-2) ft. in length and the inside edges of the frame are (x+7) ft in length. What is the total area of the frame? Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Draw a picture of this. You should be able to see that the outside area minus the inside area is the frame area. All three of these areas are square-based. The inside frame dimensions are the square painting area.
