You're trying to access a geometry property on features which does not
exist. Actually features is an array.
Instead, you should loop on those features to get the extent for each one,
and take advantage of the extend method on the Bounds class to compute the
global extent.
var extent = new OpenLayers.Bounds();
for(var i=0, len=features.length; i<len; i++) {
extent.extend(features[i].geometry.getBounds());
}
Also notice that "extent" and "extend" have different meanings in english.
