Solution: The area of the region is ( 2.2 m) ^ 2 = 4.84 m ^ 2, so the flux of a perpendicular 5.4 Tesla field would be ( 5.4 T)( 4.84 m ^ 2) = 26.13 Tm ^ 2.
Generalized Response: The flux of any vector field through an area A is equal to the product of the field strength and the area, as long as the vector field is directed perpendicular to the area. In this case we have a magnetic field B directed perpendicular to an area A, so the flux is just flux = B * A.
