Answer:
79.43 sq cm
Step-by-step explanation:
outer square
side= 14 cm
area of outer square= side × side
=14×14
= 196 sq cm
accordingly sum
diameter = d= side of inner square
d/2+d/2 +d+3+3= 14cm
2d= 14-6
d= 8/2= 4 cm
d=
area unshaded part= area of inner square + 4× area of semicircle
= side × side + 4× 1/2 π r^2
= 4×4+2× 22/7 4×4
=16+704/7
= 816/7
shaded area = outer square area - unshaded region
= 196-816/7
= 556/7= 79.4285714
= 79.43 sq cm approximately
