Quadrilateral ABCD has side lengths of AB = 3, BC = 4y – 5, CD = 3, and AD = 2y + 1. Find the value of y for which quadrilateral ABCD is a parallelogram.

OK?
@Alexissutherland97 .. i've drawn a paralleogram and as u can see i've labelled it with what so ever was provided to us.. now do you know the property of the parallelogram which says that in a parallelogram opposite sides are equal... so give it a try... by equating AD = BC
@Alexissutherland97 r u there ??
I dont know the properties of the parallegram
okay... so.. let me just give u a little view about the properties a parallelogram is a close figure made up of four sides in which the opposite sides are equal and are even parallel to each other..
if its not clear to u then go through the following link http://cbse-notes.blogspot.in/2012/10/class-9-ch8-properties-of-parallelogram.html it would clear all your doubts and has a good explanation too..!
and after that im damn sure.. you would be able to solve the question like this one very easily...:D
ok thanks
