Subtract 2 border widths from the side length
\n" ); document.write( " $\"+7x+-+2%2A12+=+7x+-+24+\"$ = width of court
\n" ); document.write( "not including border
\n" ); document.write( "Let $\"+A+\"$ = area of court not including border
\n" ); document.write( " $\"+A++=+%28+7x+-+24+%29%5E2+\"$
\n" ); document.write( " $\"+A+=+49x%5E2+-336x+%2B+576+\"$ \n" ); document.write( "
