    Given:

    Parallelogram length = 11 cm

    triangle atop the parallelogram : short leg = 7 cm

    Right triangle inside the parallelogram : long leg = 9cm

    Area of parallelogram = base * height

    A = 11cm * 9cm

    A = 99 cm²

    Area of a triangle atop the parallelogram:

    A = ab/2

    A = (11cm * 7cm) / 2

    A = 77 cm² / 2

    A = 38.5 cm²

    Total area of the figure

    99 cm² + 38.5 cm² = 137.5 cm²
