Let the width of the field be x ft.
\n" ); document.write( "So length = (2x-5) ft
\n" ); document.write( "Perimeter = 2[ length + width]
\n" ); document.write( " 2[2x-5+x] = 230
\n" ); document.write( " 2{3x-5} = 230
\n" ); document.write( " 6x - 10 = 230
\n" ); document.write( " 6x = 240
\n" ); document.write( " x = 40
\n" ); document.write( "Thus the width of the field = 40 ft.
\n" ); document.write( "Length = 2x-5
\n" ); document.write( " = 2*40 - 5
\n" ); document.write( " = 80 - 5
\n" ); document.write( " = 75
\n" ); document.write( "Width = 40 ft and length = 75 ft \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
