Algebra.Com's Answer #624553 by fractalier(6550) You can put this solution on YOUR website! Perimeter P = 2L + 2W = 44 or \n" ); document.write( "L + W = 22 \n" ); document.write( "Then we also have \n" ); document.write( "L = 7 + 4W \n" ); document.write( "Substitute that into the first equation and we get \n" ); document.write( "7 + 4W + W = 22 \n" ); document.write( "5W + 7 = 22 \n" ); document.write( "5W = 15 \n" ); document.write( "W = 3 cm \n" ); document.write( "L = 22-3 = 19 cm \n" ); document.write( " |
