Homework Help: Find two open sets A and B, such that A is subset of B, A is not equal

    Find two open sets A and B, such that A is subset of B, A is not equal to B, and m(A)=m(B)

    Can I use these two sets?

    A=(0,2) B=(0,1) U (1,2)

    thanks

    Re: measure(A)=measure(B)

    Almost. Your example has B a subset of A. You want the reverse.
