I think the question should be the below:

What is the total distance, side to side, that the top of the building moves during such an oscillation?

Answer is the below:

Acceleration ... a = (-) ω² x

(ω = equivalent ang. vel. = 2π. f) (x = displacement from equilibrium position)

x (max) = a (max) / ω²

x = (0.015 x 9.8m/s²) / (2π. f) ² ... (0.147) / (2π*0.22) ² ... ►x (max) = 0.077m ... (7.70cm)
