\n" ); document.write( "
\n" ); document.write( "Let the Height be the Width.
\n" ); document.write( "A rectangular book case, where P=2L + 2W
\n" ); document.write( "Given:
\n" ); document.write( "P=60ft
\n" ); document.write( "L=3*W
\n" ); document.write( "H=W
\n" ); document.write( "So, \"60=2%283W%29%2B2W\"---> \"60=6W%2B2W=8W\" --->\"cross%2860%297.5%2Fcross%288%29=cross%288%29W%2Fcross%288%29\"
\n" ); document.write( "W=7.5ft=Height
\n" ); document.write( "Also, L=3*7.5=22.50ft=L\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check, P=2*22.5 + 2*7.5 = 45+ 15 = 60ft\r
\n" ); document.write( "
