    Answer:

    The pressure exerted by the girl is 245,000 N/m²

    Explanation:

    Given;

    mass of the girl, m = 50 kg

    area of the girl’s shoe, A = 0.002 m²

    The pressure exerted by the girl is calculated as follows;

    P = \frac{F}{A} \\\\Where;\\F \ is \ the \ force \ exerted \ by \ girl's \ weight\\\\P = \frac{F}{A} = \frac{mg}{A} = \frac{50 \times 9.8}{0.002} = 245,000 \ N/m^2

    Therefore, the pressure exerted by the girl is 245,000 N/m²
