Interesting question!!!!!!!

For me i will assume this rectangle to be a square then Area diagonal = 2*r

=> side =

\sqrt{2* r} area =

2*r^2so my rectangle has a area less than

2*r^2 it can't be A) 2r (diagonal is itself 2r so area must be greater than this)

B) is out

C) is out : greater than B value

D) is out :is side will be some value*r => area should be in terms of

r^2 E) Last option- so correct

IMO: E _________________
