Question

in a parallelogram ABCD if ab = 2x+5,CD=y+1,AD=y+5,BC=3x-4 then wat is the ratio of AB:BC

Answer 1

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
