Apply Pythagorean theorem:
\n" ); document.write( "Let d = diagonal
\n" ); document.write( "then\r
\n" ); document.write( "\n" ); document.write( "d^2 = 80^2 + 39^2\r
\n" ); document.write( "\n" ); document.write( "d^2 = 6400 + 1521\r
\n" ); document.write( "\n" ); document.write( "d^2 = 7921\r
\n" ); document.write( "\n" ); document.write( "d = 89 feet
\n" ); document.write( "
