If we are given with only two sides of the triangle and an angle between them, the area may be determine by the equation,
A = ab(sin C) / 2
where a and b are the sides and C is the included angle. Substituting the known values,
A = (2.75 miles)(1.32 miles)(sin 35°) / 2
The area is approximately equal to 1.04 mi². Therefore, the answer is the fourth choice.
