3L=10W OR L=10W/3
\n" ); document.write( "2L+2W=130
\n" ); document.write( "2(10W/3)+2W=130
\n" ); document.write( "20W/3+2W=130
\n" ); document.write( "(20W+3*2W)/3=130
\n" ); document.write( "(20W+6W)/3=130
\n" ); document.write( "26W=3*130
\n" ); document.write( "26W=390
\n" ); document.write( "W=390/26
\n" ); document.write( "W=15 ANS. FOR THE WIDTH.
\n" ); document.write( "3L=10*15
\n" ); document.write( "3L=150
\n" ); document.write( "L=150/3
\n" ); document.write( "L=50 ANS. FOR THE LENGTH.
