    20m

    Explanation:

    Pressure = pgh

    p = density of water 1000

    kg/m^3

    g = acceleration due to gravity 9.81 m/s^2

    h is the depth of water

    Pressure = 201 kPa = 201 x 10^3 Pa

    201 x 10^3 = 1000 x 9.81 x h

    201 x 10^3 = 9810h

    h = 20.49 m

    Approximately 20 m
