touch one another. Find the area be-
tween them.
​

Answer 1

$\huge \mathcal \blue{=>}\pink{Aη} \red{s} \blue{we} \green{r✌}$

Area of shaded region = Area of square  −4× area of 1 quadrant

                                        =(2a)2−4×41×π×a2

                                        =4a2−a2π

                                        =a2(4−π)=a2(4−722)=76a2

Answer 2

$\hugeαɳรωεɾ$

Area of shaded region = Area of square −4× area of 1 quadrant

=(2a)2−4×41×π×a2

=4a2−a2π

=a2(4−π)=a2(4−722)=76a2
