A quadratic finite element approximation to an obstacle problem with nonhomogeneous data is considered, without the hypothesis that the free boundary has finite length [see \textit{F. Brezzi}, \textit{W. W. Hager} and \textit{P. A. Raviart}, Numer. Math. 28, 431--443, (1977; Zbl 0369.65030) for details]. The error bound \(O(h^{{3 \over 2} - \epsilon})\) for any \(\epsilon > 0\) is obtained.
