A 2.0-m long conducting wire is formed into a square and placed in the horizontal XY-Plane A uniform magnetic field is oriented 30.0° above the horizontal with a strength of 9.0 T. What is the magnetic flux through the square? A) 1.1 T ∙ m² B) 1.9 T ∙ m² C) 2.3 T ∙ m² D) 18 T ∙ m²

The side of the square is 0.5 m (since 2.0 m is the perimeter). The area is 0.25 m². The flux is B * A * cos(θ) = 9.0 T * 0.25 m² * cos(30°) = 1.95 T ∙ m², approximately 1.9 T ∙ m².
