\n" ); document.write( "\n" ); document.write( " . The length of a rectangular playing field is 5 ft less than twice its width.
\n" ); document.write( "If the perimeter of the playing field is 230 ft, find the length and width of the field\r
\n" ); document.write( "\n" ); document.write( " Let the width of the rectanglular field be = x ft
\n" ); document.write( " Then length of the rectanglular field = 2x-5 ft
\n" ); document.write( " perimeter of the field is = 230 ft
\n" ); document.write( " perimeter = 2(length+width)
\n" ); document.write( " 230 = 2(2x-5+x)
\n" ); document.write( " 230/2 = 3x-5
\n" ); document.write( " 115 +5 = 3x
\n" ); document.write( " 120 = 3x
\n" ); document.write( " 120/3 = x
\n" ); document.write( " x = 40 ft
\n" ); document.write( " width of the rectangular field = 40 ft
\n" ); document.write( " Length of the rectangular field = 75 ft (2*40-5= 80-5=75)
\n" ); document.write( " \n" ); document.write( "
