\n" ); document.write( "The length of a rectangle is 3 times the width. The perimenter is 96 cm. Find the width and the length.
\n" ); document.write( "I know that P= 2(L+W). But I can't figure out the correct equation to get the length and width.

\n" ); document.write( "To start, P=2(L+W) ,------> working eqn
\n" ); document.write( "But, L=3W, 3 times the width
\n" ); document.write( "So, \"P=2%283W%2BW%29\"
\n" ); document.write( "\"96=2%284W%29\"
\n" ); document.write( "\"96=8W\" -----> \"cross%2896%2912%2Fcross%288%29=cross%288%29W%2Fcross%288%29\"
\n" ); document.write( "\"W=12cm\"
\n" ); document.write( "And, \"L=3%2A12=36cm\"
\n" ); document.write( "Go back working eqn:
\n" ); document.write( "\"96=2%2836%2B12%29\"
\n" ); document.write( "\"96=2%2848%29\"
\n" ); document.write( "\"96=96\"
\n" ); document.write( "Thank you,
