Answer 2

Answer:

94.5 cm^2

Step-by-step explanation:

firstly we find the area of square

=(side)^2

=(21cm)^2

=441cm^2

now,

there are four-quartarly circles

=one-circle

radius of circle=21/2cm

area of circle=πr^2

=22/7*21/2*21/2

=693/2cm^2

=346.5cm^2

area of shaded region

= area of square-area of circle

=441.0cm^2-346.5cm^2

=94.5cm^2

Hence,the area of shaded region

=94.5cm^2

so,please mark me as a brainliest answer
