Width of border: rectangular flower bed 9' by 5'. 2 colors in the bed, one in center, one for border of the same width on all sides. If she has enough plants to cover 24 ft^2 for the border, how wide can the border be?\r
\n" ); document.write( "\n" ); document.write( "------------------------------------
\n" ); document.write( "Let the width be \"x\":
\n" ); document.write( "Area of the border ?
\n" ); document.write( "Draw the picture.
\n" ); document.write( "Top and bottom areas: (5+2x)x = 5x + 2x^2
\n" ); document.write( "Left and right side areas : 9x
\n" ); document.write( "------------------------------------
\n" ); document.write( "Area Equation:
\n" ); document.write( "2(2x^2+5x) + 2(9x) = 24
\n" ); document.write( "4x^2 + 28x - 24 = 0
\n" ); document.write( "x^2 + 7x -6 = 0
\n" ); document.write( "(x+6)(x-1) = 0
\n" ); document.write( "Positive solution:
\n" ); document.write( "x = 1 ft (the width of the border should be 1 ft)
