Find area of parallelogram ABCD if AB=8 cm,BC=4 cm and distance between the two parallel lines AB and CD is 3 cm. Find the distance between AD and BC.
Given, AB=8cm;BC=4cm
Perpendicular distance between AB and BC is DL=3cm
The area of the parallelogram =base×height
=AB×DL
=8×3=24cm2
Area of the parallelogram =base×height
=AD×BM
24=4×height
Height=6cm
So the perpendicular distance between AD and BC is 6cm
