You can put this solution on YOUR website! first find the hypotenuse of one of the triangles since both triangles have the same length sides.
12^2 + 5^2 = h^2
169 = h^2 and
h = sqrt(169) = 13
now the perimeter of one of the triangles is
12 + 5 + 13 = 30 cm
and the perimeter of both triangles = 2 * 30 = 60 cm
