A television set is a 3D shape. The image (picture) on the television screen is a 2D shape. 3D is when it has length, width, and height. 2D is only length and width.
Well, honey, a 42-inch TV typically measures around 36.6 inches in width and 20.6 inches in height. But remember, size isn't everything - it's how you use it that counts!
The answer can not be calucalted without additional information. If you only know the diagnol measurement, there are an infinite number of possible lengths for the adjoining sides. If this is a question regarding the sizing of TV screens, there are two current formats: standard, where the length to height ratio is 4:3; and letterbox (or widescreen) where the length to height ration is 16:9. Using these ratios and the diagnol length, you can calculate the length and height measurements by establishing: Length = 1.3333 * Height Then: (Diagonal)^2 = (Height)^2 + (1.3333 * Height)^2
Using Pythagoras' theorem the diagonal works out as 51 inches
