Note that the distances are expressed as links to

avoid use of decimals.

To convert square links toacres, the product is divided

Area of a parallelogram( length * width )

Where there is a remainder in thoselast five figures of acres, it is multiplied by 4 for

roods and then again any remainder inthose last five is multiplied by 40 for perches

(sic.)

Area of a triangle( base * ½ height of perpendicular )

For this 9 sided shape there is atotal of 4 bases and 7 perpendiculars

to be measured and scaledthen calculate the area of 7 triangles

to be summed together

As noted earlier there are40 perches per roodand 4 roods per acre

This now being made

simple, … it is your turn.
