By adding a three‐dimensional manifold to an eleven‐dimensional manifold in supergravity, we obtain the action ofF(R)‐gravity and find that it is anomaly‐free. We calculate the scale factor of the inflationary universe in this model and observe that it is related to the slow‐roll parameters. The tensor‐scalar ratio (Rtensor−scalar) is in good agreement with experimental data.
