I assume it is isosceles. We can use Pythagorean theorem
\n" ); document.write( "a^2 + b^2 = c^2
\n" ); document.write( "and then
\n" ); document.write( "3^3 + 4^2 = c^2
\n" ); document.write( "9 + 16 = c^2
\n" ); document.write( "25 = c^2
\n" ); document.write( "5 = c.
\n" ); document.write( "The perimeter is 3 + 4 + 5 + 5 = 17 m.
\n" ); document.write( "
\n" );
