The measurement of an acre. How many Rods by how many Rods.?

Answer 1

The above posters are quite correct in that an acre is 160 sq. rods.
The actual dimensions of the acre could be quite varied. The above poster mentioned 10 by 16 and yes that is correct. It could also be:

1 by 160
2 by 80
4 by 40
5 by 32
8 by 20
— as long as the two dimensions multiplied together equal 160
