Wrong category. You want trigonometry.

That is too broad a question, as different TVs (even if the same screen size), may have a different total TV size

The sine and cosine of theta should let you calculate the width and height.

Models depend on years of production of the TV.

That is not a TV with that screen ratio.  It may be a monitor.

This sounds like polar coordinates, but you need the angle, theta.

It should be the inverse tangent of (9/21).

The sine and cosine of theta should let you calculate the width and height.

As no one makes a TV like that, who cares ?

i think this is a math problem .....

the diagonal of 21x9 equals 22.85

21 x50 / 22.85 =45.85in ....

9x 50/22.85 = 19.69in

note: the standard aspect ratio is 4:3
