ur basically gonna subtract the area of the circle from the area of the square to get the shaded region.
area of circle = pi x 4^2 = 16 pi
area of square = 32
shaded region = 16 pi - 32 = 18.3 m squared
Area of circle MINUS area of square = shaded area
pi r^2 - s * s = shaded area
pi (4)^2 - (sqrt2) * (4 sqrt2) = shaded area You should be able to get it from here ......
