I assume you mean that each side of the base is 8m, and the height is 22m.
If you want useful answers, ask sensible questions.
So, each lateral face is a triangle with base 8
The height of each triangle is the slant height of the pyramid.
If you look from the side, the altitude from the top to the base lands in the middle, 4m from each side. So, the slant height s can be found by
4^2 + s^2 = 22^2
s = 6√13
So, the lateral area is 4 times the area of each triangle:
area = 4(8 * 6√13)/2 = 96√13 m^2
