If rectangle, y along the building, x for the each adjascent side, A for area;
\n" ); document.write( "\"2x%2By=300\", and \"A=xy\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=x%28300-2x%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The two roots for A are x=0 and 300=2x; 150=x.
\n" ); document.write( "The maximum A should be in the exact middle of these two roots:
\n" ); document.write( "\"%280%2B150%29%2F2=75\"
\n" ); document.write( "or
\n" ); document.write( "maximum A is at \"x=75\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=300-2x\"
\n" ); document.write( "\"y=300-2%2A75\"
\n" ); document.write( "\"y=150\"\r
