Area A = LW = 105 \n" ); document.write( "We also have L = 2W + 1. \n" ); document.write( "Now substitute and get \n" ); document.write( "(2W+1)W = 105 \n" ); document.write( "2W^2 + W - 105 = 0 \n" ); document.write( "Now factor and solve \n" ); document.write( "(2W + 15)(W - 7) = 0 \n" ); document.write( "so that \n" ); document.write( "W = 7 feet and \n" ); document.write( "L = 2W + 1 = 15 feet \n" ); document.write( " |
