Solution

Side of the square = 14 cm
Radius of the circle `=14/2 = 7 "cm"`
Area of the quadrant of one circle` = 1/4pi"r"^2`

`=1/4xx22/7xx7xx7`

= 38.5 cm

Area of the quadrants of four circles = 38.5 × 4 = 154 cm

Now,
Area of the square =(Side)

= 14

= 196 cm

Area of the shaded region = Area of the square -- Area of the quadrants of four circles

= 196 - 154 

= 42 cm
