P = 2L +2W
\n" ); document.write( "44 = 2L + 2W
\n" ); document.write( "L = 3W
\n" ); document.write( "Substitute
\n" ); document.write( "44 = 2(3W) + 2W
\n" ); document.write( "44 = 6W + 2W
\n" ); document.write( "44 = 8W
\n" ); document.write( "Divide each side by 8
\n" ); document.write( "44/8 = W
\n" ); document.write( "Reduce
\n" ); document.write( "5 1/2 = W
\n" ); document.write( ".
\n" ); document.write( "If you know the width is 5.5, and the length is 3*5.5, then the length is 16.5.
\n" ); document.write( "Prove it by putting in the values:
\n" ); document.write( "2(16.5) + 2(5.5) = 44
\n" ); document.write( "33 + 11 does indeed equal 44
\n" ); document.write( "
\n" );
