Question

A parallelogram abcd has sides ab=27cm. and ad=15cm. the distance between the sides ab and dc is 10cm. find the distance between the sides ad and bc.

Answer 1

Given AB 27cm and AD 15cm. So opposite sides and angles are equal in parallelogram. To find distance b/w AD and BC is take point F on line AD and join to point C so it becomes perpendicular . Now AE*DC=27*10=270.

Also area of parallelogram FC*AD =270.so FC*15=270 ...

FC =18
