Shawntelle is solving a problem involving a triangular pyramid. you hear her say that "bee" is equal to 24 inches. how can you tell if she is talking about the base area b of the pyramid or about the base b of the triangle

Shawntelle must be talking about the base (B) of the triangle.  This is because the base area (B) of the pyramid is area, so the unit must be INCHES SQUARED, not inches.  However, the base of the triangle is a one-dimensional line and so can be described by length in inches.
