Perimeter P = 2L + 2W = 76 and
\n" ); document.write( "L = W + 4
\n" ); document.write( "Now substitute and get
\n" ); document.write( "2(W+4) + 2W = 76
\n" ); document.write( "2W + 8 + 2W = 76
\n" ); document.write( "4W + 8 = 76
\n" ); document.write( "4W = 68
\n" ); document.write( "W = 17 inches
\n" ); document.write( "L = W + 4 = 21 inches
\n" ); document.write( "
