By using the given ratio, we will see that the diagonal measures 50 inches.
<h3>
How to get the diagonal of the screen?</h3>
First, we know that the ratio between length and width is 16:9, and the length is 43.6 inches, then the width will be:
W = (9/16)*43.6 inches = 24.5 in
Now, the diagonal will be equal to the hypotenuse of a right triangle with catheti of 43.6 in and 24.5 in, by using Pythagorean's theorem we get:

We conclude that the diagonal measures 50 inches.
