    The formula for the perimeter of an ellipse is given by:

    P = 2π√ ((a² + b²) / 2)

    where a and b are the semi major and semi minor axes.

    So, a = 7.5 and b = 3.75

    Substituting the values:

    P = 2π√ ((7.5² + 3.75²) / 2)

    P = 37.25 ft

    The closest answer is

    C. 37.3 ft
