Or, if a field of the same figure be 287 yards long and 

 154 yards Wide, the content will be

Again If the field be wider at one end 

 than at the other, as in the figure here re 

 presented, measure the length in the mid 

 dle, as in the first example, from A to B, 

 and the breadth in the middle from C to D, 

 and find the content as before. Now, sup 

 pose the length to be 303 yards, breadth j 

 124 yards, the content will be 



100 yards wide

But the breadth in the middle might have been found 

 by measuring both ends and adding them together, and 

 taking half their sum for a mean breadth thus : If the 

 larger end be 146 yards wide, and the lesser end be 102 

 yards wide, their sum would be 248 yards, the half of 

 which is 124 yards for a mean breadth, as above ; but 

 the method above described is a shorter way to come at 

 the result,
