    Taking D(x) or AD as the Demand curve,and market Prices as OP1 and OP2,

    Area[A.P2.B] is the consumer's surplus when price is P2.

    If Prices fall from P2 to P1,

    Then,

    Area of the Triangle[A.P1.F] is the new consumer's surplus.

    You can find the Amount of Increase by finding the differences in Areas:

    Area(AP1F) - Area(AP2B)
