p. 106 (20) A rectangular field is 12 chains 60 links long and 9 chains 35 links wide. Find, correct to the nearest shilling, the value of the crop obtained from this field at a rate of £ 11 17s. 6d. per acre.
(100 links= 1 chain; 10 sq. chains = 1 acre).
A chain is 22 yards. So a link is exactly 7.92 inches -- curious. This was a small eruption of decimality in a world dominated by factors of 2 and 3.
I'm interested in where they put the full stops, in relation to the brackets. I would have put the last one inside the right bracket.
