Two flat surfaces are exposed to a uniform, horizontal magnetic field of magnitude 0.

Two flat surfaces are exposed to a uniform, horizontal magnetic field of magnitude 0.48 T. When viewed edge-on, the first surface is tilted at an angle of 11° from the horizontal, and a net magnetic flux of 9.00 10-3 Wb passes through it. The same net magnetic flux passes through the second surface.determine area of first surface.
