Hi there,
\n" ); document.write( "Make length = x
\n" ); document.write( "width = x - 5
\n" ); document.write( "Area = length x width
\n" ); document.write( "36 = x(x - 5)
\n" ); document.write( "36 = x^2 - 5x
\n" ); document.write( "x^2 - 5x - 36 = 0
\n" ); document.write( "(x - 9)(x + 4) = 0
\n" ); document.write( "x + 4 = 0
\n" ); document.write( "x = -4 disregard as -ve
\n" ); document.write( "x - 9 = 0
\n" ); document.write( "x = 9
\n" ); document.write( "Length = 9 feet
\n" ); document.write( "Width 4 feet
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
