Exhibit A <br />Example: Non -Uniform Rectangular <br />Length line (AB) = 65 ft <br />Distance between offset lines is 13 ft apart <br />th of each offset line: <br />C=20ft F=20ft <br />D=10ft G=25ft <br />E=15ft H=20ft <br />gelengthof = (C+D+E+F+G+H) <br />lines (Number of offset lines) <br />=(20+10+15+20+25+20)/6 <br />= 18.3 ft <br />Area = (Length line) <br />x (Average length of offset lines) <br />=65ftx18.3ft <br />= 1189.5 ft <br />Irregular Rhombus or Widening Rectangular <br />A fast way to measure irregular rhombi is shown in the example below. Stake one end of the <br />measuring tape at point (A, B); measure line d and then line B. Without removing the stake <br />measure line c and then line A. Using those four measurements you will be able to find line f and <br />line e. The areas of triangle IN), triangle (ce), and rectangle (cd) can now be calculated. <br />l&� <br />
