Or, if a field of the same fgure 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 

 124 yards, the content will be

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.
