A large piece of land, divided into small plots, belongs to 5 different farmers.
Below is a plan of the area as the land is presently divided.
All the plots labelled (a) belong to farmer (a).
All the plots labelled (s) belong to farmer (s) and so on.
This piece of land must now be re-divided so that each farmer’s plots are adjacent to each other.
After the re-division each farmer must have the same area of land as before.
