    Drop a vertical at P down to the x-axis. Your trapezium should now be clear.
    Your desired area will be the area of the trapezium minus the 25 1/3.

    As a visual backup to Ghostwalkers post:



    The blue area is the integral, the green area is the area you want and the trapezium is the blue area + the green area.

    So... how do you find the green area then?
