Hi
In MGMAT Geometry Strategy guide chapter 1, Question no.10 in the excercises has a question on Picture and Frame. The square picture sits inside a bigger square frame. The question asks for the area of the picture. One side of the frame is given. I had approached this problem by first calculating the area of the frame (since it is a square and length of a side is known), but I could not proceed beyond that.
In the solution - they seem to "halved" the area of the picture ( 1/2 of Area of the Picture + Frame). I dont seem to understand this line of logical reasoning. Can somebody explain?
