1. Compute Aspect Ratio Diagonal Norm
norm = √(16² + 9²) = √337 ≈ 18.3576
2. Solve Width from Pythagorean Scale Factor
w = (16 × 65) / 18.3576 ≈ 56.65 in
3. Solve Height & Verify Area
h ≈ 31.87 in, Area ≈ 1,805.34 in²

How Screen Diagonals Map to Width & Height
TVs and monitors are always sold by corner-to-corner diagonal screen glass size D. Knowing the aspect ratio W : H (such as 16 : 9), the ratio diagonal norm equals √(16² + 9²) = √337 ≈ 18.3576.
Width = D × (W / √(W² + H²)) | Height = D × (H / √(W² + H²)) | Area = Width × Height
