Compute width and height from diagonal and aspect ratio
Posted on 8 Nov 2021 - 11:42
Problem When the information about a screen, a window or a generic rectangle is limited to its diagonal and an the aspect ratio (the width divided by the height) and we need to know width and height, we have a little problem. It must be easy right? Well.. not as obvious as most people expect (how many of your friends know the right answer?) but still the solution isn’t difficult and it’s a nice example of use of some known quadratic formulas.
