you can find the height of each triangle ...
h^2 + 5^2 = 13^2
h = 12
Area of one such triangle = (1/2)base x heigh = (1/2)(10)(12) = 60
there will be 6 such triangles
You don't say if you include the base in the surface area, if so ...
then you can find the area of one of the six equilateral triangles that form the base.

1/2 PL
P=10*6 because all sides of the hexagon r 10
L=9
60*9/2
270
