directrix · Answer

The formula for the surface area of a regular square pyramid is this:

SA = B + 1/2 *  p  *  L where B is the area of the square base, p is the perimeter of the square base, and L is the slant height of the pyramid.

directrix · Answer

You already have the value of B, the base, to be 49.

directrix · Answer

The perimeter of the base is 28.
