The electric form factor of the neutron was determined from studies of the reaction \rea{} in quasi-elastic kinematics in Hall A at Jefferson Lab. Longitudinally polarized electrons were scattered off a polarized target in which the nuclear polarization was oriented perpendicular to the momentum transfer. The scattered electrons were detected in a magnetic spectrometer in coincidence with neutrons that were registered in a large-solid-angle detector. More than doubling the $Q^2$$-range over which it is known, we find \GEn{}$$ = 0.0225 \pm 0.0017 (stat) \pm 0.0024 (syst)$, $$0.0200 \pm 0.0023 \pm 0.0018$$, and $$0.0142 \pm 0.0019 \pm 0.0013$$ for $Q^2$ = 1.72, 2.48, and 3.41~\gevsq, respectively.
