Bunuel,

Please point out where I am going wrong.

Area of rectangle/sqaure (assumption: TV is either rectangle or square) = \(\frac{d^2}{2}\) where d = diagonal.

So, doesn't question itself suffice, in this case?

"In two similar triangles (or rectangles), the ratio of their areas is the square of the ratio of their sides." - Can you explain how can this be derived with simple proof?
