ABCD is a parallelogram.AE is perpendicular on DC and CF is perpendicular on AD.ifAB=10cm;AE=8cm and CF=12cm.find AD.

Question

it is a parallelogram and AB=10cm;AE=8cm;CF=12cm

Answer 1

The conditions and measurements as given cannot exist.

 

If AB = 10, CD = 10. The perpendicular CF would be the leg of a right triangle for which CD is the hypotenuse. As the hypotenuse, CD measure must be greater than either leg of the right triangle. CF = 12 is a contradiction to the conditions of the right triangle CFD.
