What error did you correct? 

The newdata data frames in my examples have been pretty simple, and have
defined the 'area' vector simply, for instance,
new <- data.frame(area = c(8172, 10220, 11570, 24150))
new
#        area
#    1  8172
#    2 10220
#    3 11570
#    4 24150

Is something wrong with this? Were you able to make predict.lm work with
newdata = new and type = "terms"?
