Exterior angle = 40 degrees
\n" ); document.write( "Sum of all exterior angles in a polygon = 360 degrees
\n" ); document.write( " For n sided polygon , there will be n exterior angles
\n" ); document.write( " Hence for n sides, Sum of all exterior angles = n*40
\n" ); document.write( " Hence n*40= 360
\n" ); document.write( " n= 360/40
\n" ); document.write( " =9
\n" ); document.write( " there will be 9 sides
\n" ); document.write( " Let lengtt of each side be x feet
\n" ); document.write( " Hence perimeter = x+x+x+x+x+x+x+x+x
\n" ); document.write( " = 9x
\n" ); document.write( " But , perimeter = 63 feet
\n" ); document.write( " 9x =63
\n" ); document.write( " x= 63/9
\n" ); document.write( " = 7 feet
\n" ); document.write( "Hence length of each side = 7 feet\r
