Question

ABCD is a square its side is 14 cm then find the shaded part of the figure

Answer 1

area = 2× 22/7× 7×7 + 2× 1/2×14×7
area= 406 cm^2

Answer 2

the area of shaded region is 

radius of the circle is 7

2( $\pi r ^{2}$ ) + 2 $(\frac{ \sqrt{3} }{4})a ^{2}$

= 2 ( $\frac{22}{7}$ x 7(7)) + 1/2 ( 14 x 14 )

= 2 ( 22 (7)) + 7(14)

= 308 + 98

= 406 $cm^{2}$
