Answer :

side of square (a) = 8 cm

from the fig. we can see that of circle is placed at four parts of the square. if we join them a circle is formed with radius (r_{1}) 2 cm

Another circle is placed at centre of the square with radius (r_{2}) 2 cm

Area of colored region = Area of square - Area of circles at 4 corners + Area of circle at centre

= a^{2} – (4 × ( × r_{1}^{2}) + (π r_{2}^{2}))

= a^{2} – (π r_{1}^{2} + π r_{2}^{2})

= 8^{2} – (3.14 (2^{2} + 2^{2}))

= 38.88 cm^{2}
