    13.76 square meters

    Step-by-step explanation:

    The side of square is 8 meters.

    So, the diameter of circle = 8 meters.

    ⇒ Radius = (diameter of circle) : 2 = 8 : 2 = 4 meters

    Shaded region = Area of square - Area of circle

    = (Side * Side) - π * (radius) ²

    = 8 * 8 - π * 4 * 4 {∵ π = 3.14 or 22:7}

    = 64 - 50.24

    = 13.76 square meter
