Perimeter (think, a fence around) equals 2 width + 2 length
\n" ); document.write( "P = 2W + 2L
\n" ); document.write( "18 = 2W + 2L
\n" ); document.write( "Divide by 2
\n" ); document.write( "9 = W + L
\n" ); document.write( "L = W+5
\n" ); document.write( "Substitute the value of L into the equation above it.
\n" ); document.write( "9 = W+L
\n" ); document.write( "9 = W+(W+5)
\n" ); document.write( "9 = 2W+5
\n" ); document.write( "Subtract 5 from each side
\n" ); document.write( "4 = 2W
\n" ); document.write( "Divide each side by 2
\n" ); document.write( "2 = W
\n" ); document.write( "If the width is 2, then the length is 5 more than that, or 7
\n" ); document.write( "W = 2; L = 7
\n" ); document.write( "P = 2+2+7+7, or 18
\n" ); document.write( "
\n" );
