Carter fenced in a rectangular plot of land and then divided it into two halves by putting another fence along the main diagonal. This diagonal fence measured 41 metres exactly.

Martindale also fenced in a rectangular plot of land in a similar way (including the diagonal fence) but his rectangle was one-third greater in area than Carter's plot and used less fencing.

In both plots all the the dimensions (lengths, widths and diagonals) were a whole number of metres.

How much more fencing did Carter use than Martindale?
