You can put this solution on YOUR website!
Assign variables to everything you can unless already assigned in the description and write the numeric facts that the description indicates.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = height
\n" ); document.write( "y = area
\n" ); document.write( "u = length (could be any other variable not yet assigned)
\n" ); document.write( "-
\n" ); document.write( "u=4+x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The description can give you a relationship for all of these using formula for area: $\"Length%2AHeight=Area\"$ ;\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area, $\"y=x%2Au\"$ , or $\"y=x%28x%2B4%29\"$ , or if you want to solve the length equation for x, you can show y as a function of u. \n" ); document.write( "

\n" );
