##### Solution :-

Side of square = 14 cm

Four quadrants are included in the four sides of the square.

Radius of the circles = $$\dfrac{14}{2}$$ cm = 7 cm

Area of the square ABCD = 14= 196 cm2

Area of the quadrant = $$\dfrac{πR^2}{4}$$ cm2 = ($$\dfrac{22}{7}$$) ×$$\dfrac{7^2}{4}$$ cm2

$$\dfrac{77}{2}$$ cm2

Total area of the quadrant = 4×$$\dfrac{77}{2}$$ cm= 154cm2

Area of the shaded region = Area of the square ABCD – Area of the quadrant

= 196 cm– 154 cm2

= 42 cm2
