    Area of the square = (20x) ²

    Area of the circle = πr² = π (4x) ²

    (20x) ² = 20x * 20x = 400x²

    π * (4x) ² = 16x²π

    Total area = (400x²) - 16x²π

    Total area = x² (400 - 16π)

    Total area = x² 16 * (25 - π)

    Total area = 16x² (25 - π)

    Area of squre=legnth times legnth so area of square = (20x) ^2=400x^2 area of circle=pi times r^2 pi times (4x) ^2 pi times 16x^2 aprox 50.27x^2 so 400x^2-50.27x^2=349.73x^2
