The govt. decides to give farmers a special bonus for each row of four trees they plant. An intelligent farmer found a way of planting five such rows of trees - but the surprising fact is that he did it with only ten trees. How was it possible?

The farmer planted his trees in a star pattern.
If you draw a star, place a tree at the 5 points of the star and at each place where the lines cross.
