Algebra.Com's Answer #648769 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Perimeter P = 60 = 2L + 2W \n" ); document.write( "We can also write \n" ); document.write( "L = 2W + 2 \n" ); document.write( "Now plug that in to the above and get \n" ); document.write( "60 = 2(2W + 2) + 2W \n" ); document.write( "60 = 4W + 4 + 2W \n" ); document.write( "6W + 4 = 60 \n" ); document.write( "6W = 56 \n" ); document.write( "W = 56/6 = 28/3 inches \n" ); document.write( "so that \n" ); document.write( "L = 2(28/3) + 2 = 62/3 inches \n" ); document.write( " |
