In the given figu

Answer :

Given:

Side of square = 7 cm


Radius of each quadrant = 7 cm


Area of square = side × side = 7 × 7 = 49 cm2


Area of quadrant = πr2


Area of 2 quadrants = 2 × × πr2


= × × 7 × 7


= 77 cm2


Area of shaded region = Area of 2 quadrants – Area of square


= 77 – 49 = 28 cm2


Hence, the area of shaded region is 28 cm2.
