    Answer: (1) 96 sq. cm.
    Explanation:-
    Given-

    RE: What are the Area of the Rhombus


    Side of a rhombus = 10 cm   and one diagonal = 16 cm
    In right angle triangle COD
    OC2 = 102 – 82 = 100 – 64 = 36
    OC = 6
    Other diagonal BD = 2 x 6 = 12 cm
    Formula-
    Area of a rhombus = AC x BD/2                         (where, AC, BD are the diagonals of the rhombus)
    Then, Area of rhombus ABCD = 12 x 16/2
    = 192/2 = 96 sq. cm
    Hence, the answer is (1) 96 sq. cm.
