Let length be L, and width, W
\n" );
document.write( "Then, W = L + 3
\n" );
document.write( "2(L + W) = 2(15)
\n" );
document.write( "L + W = 15
\n" );
document.write( "L + L + 3 = 15 ----- Substituting L + 3 for W
\n" );
document.write( "2L = 15 - 3
\n" );
document.write( "2L = 12
\n" );
document.write( "L, or length = , or
