A rectangular garden is to be surrounded by a walkway of constant width.(X SAY) The garden's dimensions are 30 ft. by 40ft.
\n" ); document.write( " The total area, garden plus walkway, is to be 1800ft^2.
\n" ); document.write( "L OF GARDEN AND PATH =X+40+X=2X+40
\n" ); document.write( "W OF GARDEN AND PATH = X+30+X=2X+30
\n" ); document.write( "AREA OF GARDEN AND PATH = (2X+40)(2X+30)=1800
\n" ); document.write( "4X^2+140X+1200=1800
\n" ); document.write( "4X^2+140X-600=0
\n" ); document.write( "X^2+35X-150=0
\n" ); document.write( "X = [-35+ OR - SQRT(35^2+4*1*150)]/2 =3.86
\n" ); document.write( "A IS THE ANSWER\r
