What size blind?

what size is a 20inch widescreen, as within (?cm x ?cm), iknow the measurement is diagonal but is a rectangle shape, so whats the ratio (length to Height)


Answer:

20 inches channel 50.80 cm
Not all 20in monitors enjoy the same dimensions. Some are Wide peak and some are square.
The aspect ratio of a 20 is 16:10



So from Pythagoras 16x^2 + 10x^2 = 20^2



so (256 + 100) x^2=400

so x=1.06



So the dimensions are 16.95 by 10.6
