A typical Samsung 50 inch plasma TV has a width of 48 inches. It has a viewing screen diagonal of 50 inches. It typically 3 inches thick, and has a height of 30 inches.
Using Pythagoras' theorem the diagonal works out as 51 inches
21 inches is the diagonal measure of the screen in a 21-inch TV.
4 feet high by 8 feet wide = diagonal of 107.28 inches.
A rectangular prism with a width of 4 inches a height of 6 inches and a depth of 8 inches has a volume of 192 cubic inches.
The average price of a 50 inches diagonal plasma TV is $1199.99. This particular one has a Wifi capability and a thin frame. This product is manufactured by LG electronics.
Televisions and monitors are measured by the diagonal distance from opposite corners of the screen. For example a 20" TV is measuring the diagonal distance (like the hypotenuse of a triangle). The width and the height will be less than 20". Since televisions have gone completely LCD or plasma, the smallest commonly available is 19". The largest I have seen is 54" - there may be some larger.
Diagonal = sqrt(36 + 25) ie sqrt 61 which is 7.8 inchesto the nearest tenth.

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
The actual dimensions of a 24-inch flat screen TV will vary depending on the type of display. The height can be as little as 9.5 inches or as big as 12.72 inches. The width only varies a small amount from about 20-22 inches.
