In a parallelogram ABCD,it is given that AB=16 cm and altitude corresponding to the sides AB and AD are 6cm and 8 cm respectively . Find the length of AD

AREA  OF ABCD  = BREATH  * HIEGHT 
                              = 16*8
                             = 128 CM  
ALSO AREA OF ABCD = AD*10
BUT AREA WILL REMAIN  SAME 
SO,  128=AD*10
AD=128/10  
 AD=12.8 CM               ANSWER    IS   12.8  CM
