13 METHOD OP 



Once more If one side of a piece of 

 land be longer than the other, take the 

 length and breadth exactly in the mid 

 dle, and you will be able to find the con 

 tent precisely as in the last example. 

 Now, suppose the length from A to B 

 318 yards, the breadth from C to D 129 

 yards (

Content, 8 1 36 



The content of the triangle 

 is found by measuring the 

 longest side, and also the 

 nearest or perpendicular dis 

 tance from the said side to 

 the corner opposite to the 

 said side ; and in finding the 

 content, observe to take only 

 one half the perpendicular Q 

 for a mean width. Now, sup 

 pose the longest side, B C, be 417 yards, and the per 

 pendicular, A D, be 326 yards, the half of which is 163 

 yards for a mean width ; then

And the content of any field, having four straight side&, 

 may be found by the same rule : measure the distance
