The lateral area is the sum of the areas of the 4 triangles that form the faces of the pyramid. The area of one of the triangles is %28bh%29%2F2 where b is the base of the triangle (equal to the side length of the base of the pyramid) and h is the altitude of the triangle (equal to the slant height of the pyramid).

So the lateral area is 4%2A%28bh%29%2F2=2bh=2%286%29%285%29
