TABLE V. LENGTHS AND BREADTHS WHICH GIVE AN ACRE. 181 



To find the breadth required by calculation. Reduce the 

 quantity to be set off, to the same denomination as the given 

 length, divide the quantity so reduced, by the length, and the 

 quotient will be the breadth required, and in the same name or 

 denomination as the two factors. 



The following is an arithmetical solution of the last example.

If it be required to set off a certain quantity from the side ot 

 a field, the side boundary being irregular, but the two ends of the 

 field parallel ; the content of the irregular portion or off set, must 

 first be found in the usual manner, and deducted from the given 

 quantity ; the width for the remaining portion will be found from 

 the Table as directed above. 



^ EXAMPLE. It is required to set off 2f acres from the irregular 

 side of a field, of which the end boundaries are parallel ; the length 

 between the two parallel ends being 133 yards, and the content 

 of the off-set, or irregular portion, having been ascertained to be 

 35 poles ; what width of the rectangular portion of the field will 

 be necessary to contain along with the off-set the required 2j 

 acres?
