Answer:
Step-by-step explanation:
In above they given a parllelogram
Area of a parllelogram= b*h
i.e,12*9=108
are of KPJ=1/2*b*h
=1/2*4*9
=18
area of MPN
=1*2*PN*MN
=1/2*12-4*9
=1/2*8*9
=36
AREA OF SHADED REGION =
AREA OF PARLLELOGRAM-(AREA OF KPJ+AREA OF MNP)
=108-(18+36)
=108-54
=54
OPTION (A) IS CORRECT
