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?

Bunuel,

Please point out where I am going wrong. May be I am getting confused here..

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

"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?

Area of rectangle does not equal to \frac{d^2}{2}.
