A hobby gardner wishes to use 81 ft of fencing to enclose a rectangular gardner and sub divide region into two smaller areas. If the total enclosed is 264 ft squared find the dimensions of the enclosed region.
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "Draw the picture of the rectangle with a vertical dividing line to create
\n" ); document.write( "the two smaller areas.
\n" ); document.write( "------------------------
\n" ); document.write( "Let the dividing line and 2 parallel sides be of length \"x\" ft.
\n" ); document.write( "-----------
\n" ); document.write( "That leaves (81-3x) ft. of fencing for the top and the bottom sides.
\n" ); document.write( "Each of those sides will then be (81-3x)/2 ft. in length.
\n" ); document.write( "--------------------------------------------------------------
\n" ); document.write( "The area will be [(81-3x)/2]*x = 265 sq. ft.
\n" ); document.write( "81x - 3x^2 = 530
\n" ); document.write( "3x^2 - 81x + 530 = 0
\n" ); document.write( "---------------------------------------
\n" ); document.write( "x = [81 +- sqrt(81^2 -4*3*530)]/6\r
\n" ); document.write( "\n" ); document.write( "x = [81 +- sqrt(201)]6\r
\n" ); document.write( "\n" ); document.write( "Positive solution:\r
\n" ); document.write( "\n" ); document.write( "x = [81 + 14.18]/6 ft
\n" ); document.write( "x = 15.86 ft.
