MEASURING LAND. 



Again, suppose a piece 

 of land of the following 

 shape and dimensions: 

 A D 232 yards, B E 143 

 yards, C F 84 yards, and 

 B D 200 yards ; the distance 

 from the straight line B D 

 to the curve at B, nothing, 

 at G 15 yards, at H 8 yards, 

 at I nothing, and at the end 

 D 14 yards; also, the line 

 A C 160 yards long, and 



the distance from the end 



A of the straight line to the 



curve 23 yards, at L nothing, at M nothing, and at the 

 end C 11 yards. From these dimensions, the content is 

 found in the following manner : The two perpendicular 

 distances B E and C F, when added together, make 227, 

 the half of which is 113 for a mean width of the square 

 part : and to obtain a mean width of the curves, the off 

 sets will stand in the following manner :
