Algebra.Com's Answer #786826 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "A solution using formal algebra is something you should know how to do. However, if a formal solution is not required and the objective is only to solve the problem as quickly as possible, then mental arithmetic will find the answer. \n" ); document.write( "The perimeter is 72, so length plus width is 36. So you need two numbers whose sum is 36 and whose product is 308. \n" ); document.write( "So find pairs of numbers with a product of 308 and look for one for which the sum is 36. \n" ); document.write( "308*1 no \n" ); document.write( "154*2 no \n" ); document.write( "77*4 no \n" ); document.write( "44*7 no \n" ); document.write( "22*14 YES! \n" ); document.write( " \n" ); document.write( " |
