    PQ = QR = RS = SP = 6 cm
    PA = 2AS and PA + AS = 6cm
    => PA = 4 cm and AS = 2 cm
    Similarly, RB = 2BS and RB + BS = 6 cm
    => RB = 4 cm and BS = 2cm
    Area of △ ABQ = area of PQRS - area of △APQ - area of △RBQ - area of △ASB
     = (36 - 12 - 12 - 2) sq. cm
    = 10 sq. cm
    Hence, option C is the correct answer.
