 The following is an example implementation:

     /**
      * APIMethod: calculateBounds
      * Recalculate the bounds for the polygon.
      */
     calculateBounds: function() {
         if ( this.components && (this.components.length > 0)) {
             var minx = Infinity;
             var maxx = -Infinity;
             var miny = Infinity;
             var maxy = -Infinity;
             for(var i=0; i<this.components[0].components.length; i++) {
               var x = this.components[0].components[i].x;
               minx = Math.min(minx, x);
               maxx = Math.max(maxx, x);
               var y = this.components[0].components[i].y;
               miny = Math.min(miny, y);
               maxy = Math.max(maxy, y);
             }
             return new OpenLayers.Bounds(minx, miny, maxx, maxy);
         }
     },
