apply pythagoras ..
Dia^2 = 30^2 + 20^2
Dia ^2 = 1300
Dia = 36.05

i know it isn't a rectangle....but why??

nubeer · Answer

oops sorry didn't see it .. well if it was a rectangle then the value would be exact 36

anonymous · Answer

owh...but its a four point question. so the answer shud be in four sentences

nubeer · Answer

you have to show all these calculations too that rectangle diagonal is not exact 36. this would be also carrying marks i think 2 marks for solving 1 for your "yes" or "no" and 1 mark for explanation.

anonymous · Answer

nope....solving has no marks.... 1 mark for the yes or no and 4 marks for the explanation...

nubeer · Answer

lol that's bit tricky .. even i dont know what to right for 4 marks..
As per calculated the value of the diagonal is not exact 36 that means the frame is not a rectangle. it can be rohmbous or (hmm forgot name)its kind of titled rectangle.
