Your pedal itself looks OK, but the crank arm is bent. Back in the day of steel crank arms we'd straighten these by removing the pedal (RH thread on right pedal, Left thread on left pedal) slipping a pipe over the arm and straightening it on the bike in 3 seconds.

Unfortunately aluminum cranks aren't as ductile, and can be very unforgiving of this kind of abuse. Breaking a crank is never fun; they break at inopportune times, usually at the moment of maximum load, and can cause serious injury in the form of a gash from the sharp broken end, broken ankles, or legs when the foot slams into the ground. Since there's no way of predicting if or when a straightened crank will snap, sane people don't straighten them.

A complete new crank with chainrings attached can be had fairly cheaply, but most shops tend to only sell models of a higher range then yours. If there's a local bike co-op in your town that's your best bet.
