Question

In the square ABCD with sides 2a with the

vertices of the square as centre and ½ the sides

of radius, four sectors have been given​
find the area of the shaded region

Answer 1

Answer:

6/7 a2

Step-by-step explanation:

area of shaded region = area of square - 4   x   area of one quarter

                                      =(side)2 - 4  x  πr2/4

                                      =(2a)2 - π a2

                                       =4a2 - πa2

                                       =(4 - π)2

                                        =(4 - 22/7) a2

                                        =28-22/7 a2

                                        =6/7 a2
