Side of square = 50 m
Radius of all 4 quadrants = half of side
=> radius, r = 25 m
Now,
Area of the shaded region = Area of square - area of four quadrants
=> area = side² - 4×1/4 × πr²
=> area = 50×50 - π × 25 × 25
=> area = 2500 - 625π
=> area = 625( 4 - π )
=> area = 537.5
You can also write it as 625 ( 4 - π ) m² , Its fine.
537.5 m²
