Algebra.Com's Answer #630329 by fractalier(6550) You can put this solution on YOUR website! Perimeter P = 2L + 2W = 130. We also know \n" ); document.write( "L = 5 + (1/3)W or \n" ); document.write( "L - 5 = (1/3)W or \n" ); document.write( "W = 3L - 15 \n" ); document.write( "Now substitute this into the first equation and get \n" ); document.write( "2L + 2(3L - 15) = 130 \n" ); document.write( "2L + 6L - 30 = 130 \n" ); document.write( "8L - 30 = 130 \n" ); document.write( "8L = 160 \n" ); document.write( "L = 20 inches \n" ); document.write( "W = 3(20) - 15 = 45 inches \n" ); document.write( " |
