Algebra.Com's Answer #185479 by drk(1908)![]() ![]() ![]() You can put this solution on YOUR website! Let X and Y be the two numbers. \n" ); document.write( "WE ned a formula for sum: \n" ); document.write( "(i) \n" ); document.write( "we need a formula for area: \n" ); document.write( "(ii) \n" ); document.write( "Now, maximum quadrilaterals are squares. \n" ); document.write( "So, x = y = 20. \n" ); document.write( "20 + 20 = 40 \n" ); document.write( "20 * 20 = 400 (max product) \n" ); document.write( "So, our coordinate is (20,20) \n" ); document.write( " |
