Question

Abcd is a parallelogam x and y are midpoints of bc and cd prove that ar(axy)=3/8ar(iigm abcd

Answer 1

Answer:

Since X and Y are the mid points of sides BC and CD respectively, In ∆BCD, XY|| BD and XY = BD. Since parallelogram ABCD and ∆ABX are between the same parallel lines AD and BC and BX = BC. ... Since parallelogram ABCD and ∆ABX are between the same parallel lines AD and BC and BX = BC.
