You can put this solution on YOUR website!
perimeter (the distance around) is two lengths plus two widths ___ P = 2L + 2W\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for this rug ___ \"The length is 2 times as long as the width\" ___ L = 2W\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since they are equal, you can substitute L for 2W in the perimeter equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P = 2L + (L) ___ 78 = 3L ___ L = 26\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting 26 for L ___ (26) = 2W ___ 13 = W
\n" ); document.write( "
\n" );
