In this problem we have \n" ); document.write( "A = LW = 48 and \n" ); document.write( "L = W + 2 \n" ); document.write( "Now substitute this into the first equation and get \n" ); document.write( "(W + 2)(W) = 48 \n" ); document.write( "W^2 + 2W - 48 = 0 \n" ); document.write( "(W + 8)(W - 6) = 0 \n" ); document.write( "so the width is 6 feet \n" ); document.write( "The length must then be 8 feet. \n" ); document.write( "The border fence must be the perimeter... \n" ); document.write( "P = 2L + 2W = 2(8) + 2(6) = 28 feet \n" ); document.write( " |
