Algebra.Com's Answer #613110 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Choosing L for length and W for width, the first statement reads\r \n" ); document.write( "\n" ); document.write( "L = 1.8W\r \n" ); document.write( "\n" ); document.write( "Then, for perimeter, we have\r \n" ); document.write( "\n" ); document.write( "P = 2L + 2W = 27\r \n" ); document.write( "\n" ); document.write( "We substitute and get\r \n" ); document.write( "\n" ); document.write( "2(1.8W) + 2W = 27 \n" ); document.write( "3.6W + 2W = 27 \n" ); document.write( "5.6W = 27 \n" ); document.write( "W = 27/5.6 = 270/56 = 135/28 \n" ); document.write( "L = 1.8W = (9/5)W = (9/5)(135/28) = 243/28 \n" ); document.write( " |
