    Area of a rhombus is 96 m2. If one diagonal of the rhombus is 12 m, find the length of the second diagonal.

    ক)
    8 m
    খ)
    12 m
    গ)
    16 m
    ঘ)
    24 m

    Explanation

    Area of  rhombus = 12×d1×d2{1 \over 2} \times {d_1} \times {d_2} Where d­ 1 and d 2 are the diagonals of the rhombus, \eqalign{ & \Rightarrow 96\ {m^2} = {1 \over 2}{d_1} \times {d_2} \cr & \Rightarrow {d_2} = 16\ m \cr} Hence, length of the second diagonal would be 16 m.
