1. Can we say this: Area of square is x*x For parallelogram, left side is given as x ... so its height will be Please correct my assumption.

Thanks Arj for your help.

Thank you all. :)

Thanks a lot. " In other words you end up with a square of side 'x' and a rhomd with side 'x', in which case the answer is A." I think you don't know the length of diagonals. So, how can you calculate it A ?

Please show the procedure of 2 and 3. All of these answers are correct. Thanks.
