Question

find area of shaded region​

Answer 1

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
