Question

in the figure abcd is parallelogram. if de=4cm then find bf​

Answer 1

Answer:

Step-by-step explanation:DC=6cm

Therefore AB=6cm(opposite side of parallelogram are equal in length)

DE=4cm

AREA of parallelogram ABCD=base *height

                                                  =AB*DE

                                                  =6*4=24cm^2

CB=3cm

therefore DA=3cm(opposite of parallelogram are equal)

AREA of parallelogram =base*height

                                       =DA*BF

                           24        =3*BF

                            24/3     =BF

                               BF     =8cm
