Given:

Side of square = 7 cm

Radius of the quadrant = 7 cm

Area of square = side × side

= 7 × 7 = 49 cm²

∵ Area of circle = πr²

∴ Area of a quadrant = πr²

= × × 7 × 7

= = 38.5 cm²

Thus, the area of shaded region = Area of square – Area of quadrant

= 49 – 38.5 = 10.5 cm²

Hence, the area of the shaded region is 10.5 cm².
