Basically they are asking for the surface area of this square pyramid.

where B is area of base, P is perimeter of base, l is slant height.
Area of base = 9*9 = 81
Perimeter of base = 4*9 = 36
Slant height can be found using Pythagorean theorem:
where slant height is the hypotenuse, the vertical height is one leg, and half the length of a side of base is other leg.

Now compute surface area:
