2. Relevant equations

[tex]B= \frac { \mu _0}{2 \pi r}I[/tex]

[tex]d \phi = \vec{B} \cdot d \vec {A}[/tex]

3. The attempt at a solution

I know the magnetic field of the conductor is [tex]B= \frac { \mu _0}{2 \pi r}I[/tex]. And in order to solve the magnetic flux I need to integrate [tex]d \phi = \vec{B} \cdot d \vec {A}[/tex]. But the question is, since the area is not square or rectangular, can I simply integrate over the whole area at once or do I need to cut the integral into pieces?
