Ans 3:

Class : Class 7
it is extremely obvious that the shaded area needs to be subtracted twice as the shaded area is occurring in both shapes!!!!!!!! even if u find the area of the unshaded area separately, u are going to get the same answer!!!!!!!!!!!!!!!! it is definitely C!!!!!!! (C) (C)

Ans 4:

2 times cause it overlaps on 2 shapes
