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
