Hi there,
\n" ); document.write( "Make length = x
\n" ); document.write( "Width = x - 4
\n" ); document.write( "Area of rectangle
\n" ); document.write( "= width x length
\n" ); document.write( "252 = (x - 4) * x (* times)
\n" ); document.write( "x^2 - 4x = 252
\n" ); document.write( "x^2 - 4x - 252 = 0
\n" ); document.write( "(x - 18)(x + 14) = 0
\n" ); document.write( "x + 14 = 0
\n" ); document.write( "x = -14 (Disregard as -ve value)
\n" ); document.write( "x - 18 = 0
\n" ); document.write( "x = 18
\n" ); document.write( "Length = 18 feet
\n" ); document.write( "Width = 14 feet.
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
