let the length of rectangle be ...L
\n" ); document.write( "let the width of rectangle be ...W
\n" ); document.write( " three times width = 3w = L
\n" ); document.write( " perimeter =2*L+2*W= 128
\n" ); document.write( " 2*3*W+2*W = 128
\n" ); document.write( " 8*W = 128....
\n" ); document.write( " W = 128/8 = 16
\n" ); document.write( " L=3*W=3*16 = 48
\n" ); document.write( "
\n" ); document.write( "
\n" );
