8x for the square, and w and L for the rectangle. The reason why 8x is because the description gives it that way for the square.\r

\n" ); document.write( "\n" ); document.write( "Simplify the perimeter equation and substitute for w and for L in this perimeter equation.

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use x to find value of L.
\n" ); document.write( "\"L=5%2818%2F11%29%2B8\"
\n" ); document.write( "\"L=%285%2A18%2B88%29%2F11\"
\n" ); document.write( "\"highlight%28L=178%2F11%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The solution here did not yet include finding the perimeters of the two figures, but you can now do this because w, x, and L are now all found and known.
