These are also incorrect actually! The middle one will be x(1+rt2), the same as the “circumscribing” square…for the others you will have to do (rather painful) Pythagoras applications and hence you would rarely be expected to find them in an exam scenario (which is why I left it as a homework exercise, more from the point of view of developing a comfort with geometry)
Longest – 5x^2
Middle – 2x
Sir, how to get the last one ?
