发帖数: 9094 | 3 This is a joke. How come the side of 25 (red, rectangle) changed into 35 (
red, square)?
And the side of 14 in rectangle changed into 10 in square.
No this is not the correct answer to the original question, but an optical
illusion. |

发帖数: 9094 | 10 That is correct! It shows a general approach to convert a rectangle to a
square if certain ratio is not exceeded. A brilliant approach. My poor eyes
