Answer:-
In the square
[tex]\boxed{\sf Area_{(Square)}=(side)^2}[/tex]
[tex]\\ \sf\longmapsto Area_{(Square)}=(14)^2[/tex]
[tex]\\ \sf\longmapsto Area_{(Square)}=196cm^2[/tex]
____________________________
In the circle
[tex]\boxed{\sf Area_{(circle)}=\pi r^2}[/tex]
[tex]\\ \sf\longmapsto Area_{(Circle)}=\dfrac{22}{7}\times 7^2 [/tex]
[tex]\\ \sf\longmapsto Area_{(Circle)}=22\times 7[/tex]
[tex]\\ \sf\longmapsto Area_{(Circle)}=154cm^2[/tex]
___________________________
[tex]\\ \sf\longmapsto Area_{(Waste)}=Area_{(Square)}-Area_{(Circle)}[/tex]
[tex]\\ \sf\longmapsto Area_{(Waste)}=196-154[/tex]
[tex]\\ \sf\longmapsto Area_{(Waste)}=42cm^2[/tex]
