Question 143334
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 {{{(bh)/2}}} 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*(bh)/2=2bh=2(6)(5)}}}
