Let ABCDEFG be the plot of land of 1 acre, it is required to cut a piece of land of an extent of 0.60 acres.
- Join Any points such as G and D (nearly partition line) and find the area of DEFG.In our example, we get it as 0.50 acres. We may require 0.10 acres to be cut off.
- Multiply 0.10 acres by 10 to convert it into square chains. we get the value as 1 sq. chains.
- Measure the line GD(203 links=2.03chains). Divide 1 by 1.015(which is half of the 2.03chains) and the quotient will be 0.985chains(98.5links), which is perpendicular to the line GD for the triangle of extent 0.10 acres whose base is 2.03 chains.
- Draw the lines GH, DH and DEFGH will be the area required. If the area of DEFG is found to be more than required to be taken off, then the triangle should be measured on the opposite side to the line GD shown in Sketch.
- Similarly, If we want to cut out a rectangular shape, then use the rectangular formula A=L x B.
