Toni has 16 feet of edging to make a flower garden.She wants the garden to have the greastest possible area. What dimensions should the garden have? \n" ); document.write( "--------------- \n" ); document.write( "If a circle: \n" ); document.write( "Perimeter = (pi)d = 16 \n" ); document.write( "diameter = 16/pi \n" ); document.write( "radius = 8/pi \n" ); document.write( "Area = (pi)(8/pi)^2 = 64/pi sq ft. is approximately 20.3718.. sq ft \n" ); document.write( "----------------------- \n" ); document.write( "If a rectangle: \n" ); document.write( "P = 2(l + w) = 16 \n" ); document.write( "l+w = 8 \n" ); document.write( "Area = l*w = (8-w)w = -w^2+8w \n" ); document.write( "Maximum area occurs when w = -b/2a = -8/(-2) = 4 \n" ); document.write( "Then l + 4 = 8 \n" ); document.write( "And l = 4. \n" ); document.write( "Area = 4*4 = 16 sq. ft. \n" ); document.write( "----------------- \n" ); document.write( "Conclusion: \n" ); document.write( "Max area is a circle with perimeter = 16 ft. \n" ); document.write( "============ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
