I think they threw in the fact that the swan "is 4 ft. long" to throw you off (since it's extra info that you don't need)

L=2.43%2AW%5E0.3326 Start with the given equation


L=2.43%2A25%5E0.3326 Plug in W=25


L=2.43%2A2.917 Raise 25 to the 0.3326th power to get 2.917


L=7.08831 Multiply 2.43 and 2.917 to get 7.08831


So the approximate wingspan (we introduced rounding errors) is about 7.09 feet (rounded to the nearest hundredth).
