x = 45 + (bottom leg of side triangle * 2)
Using Pythagorean formula we can find:
bottom leg of side triangle= (50^2-40^2)^1/2=30
x=45+30+30=105

Answer D


side of two parallelogram should be 45 plus plus 45 .
So answer can be 90
option B

Sorry, I do not understand your logic.
Could you please specify your line of reasoning.
