Step-by-step explanation:
ABCD is a parallelogram.
CD∥AB
∴ CD∥AE [ Extended part of parallel side ]
⇒ Area of parallelogram ABCD=AB×CE [ Since, CE situated between same parallel lines ]
=12×6.2
=744cm
2
---- ( 1 )
⇒ Area of a parallelogram ABCD=AD×BF
=8×BF ----- ( 2 )
Comparing ( 1 ) and ( 2 ) we get,
⇒ 8×BF=744
⇒ BF=
8
744
=93cm
∴ The area of parallelogram ABCD is 744cm
2
and the length of BF is 93cm.
