the area of shaded region = area(Square) - 4area(quadrant of circle) area of circle = pi r² so area of quadrant = 1/4 pi * r²
therefore area of square = 4*4=16cm²
area of 4 quadrants = 1/4 * 22/7*4*4= 88/7 cm²
subtracting it from area of square we have 16-88/7=(112-88)/7 = 24/7 cm2
therefore area of square = 4*4=16cm²
area of 4 quadrants = 1/4 * 22/7*4*4= 88/7 cm²
subtracting it from area of square we have 16-88/7=(112-88)/7 = 24/7 cm2
