ANSWER

In a parallelogram opposite side are congruent

Hence AB=CD and BC=AD

Now 2x+5=y+1 and 3x−4=y+5

On solving these equations we will get

2x−y=−4......(1)

And 3x−y=9......(2)

Now on solving these equation, we will get x=13 and y=30

Hence AB=2x+5=2(13)+5=31

And BC=3x−4=3(13)−4=35

Hence AB:BC=31:35
