What is the length of a diagonal of a rectangle whose sides measure twelve inches and five inches?
The length of the diagonal is 13.
How do you find the height and width of a diagonal?
But we need to transform it to our needs:
- height = diagonal / √(AR²+1) , where AR is the aspect ratio. height = 5.8″ / √((16/9)² + 1) = 5.8″ / 2.04 = 2.84″
- width = AR * height. width = (16/9) * 2.84″ = 5.06″
- area = height * width. area = 2.84″ * 5.06″ = 14.37 in²
Is the diagonal of a square the same as the length?
