There are different formulas:
1. Area = Base * Height / 2
2. Let s = (a+b+c)/2 where a, b, c are sides, then sqrt(s(s-a)(s-b)(s-c)) is the area.

Area =( Base x height)/2

So, obviously the area of the square at the base is found by a^2. The slant height of the pyramid can be found using pythagoras (slant height = sq. rt. ((1/2 base)^2 + height*2) After that, find surface area by: s. area = base area + 1/2 perimeter * slant height.

Area=1/2b*h
one half base times height

area can be stated several ways:
1/2 base * altitude
1/2 a b sin(C) where a and b are lengths of the sides that make angle C
sqrt (s(s-a)(s-b)(s-c)) (Heron's formula)
where s is the semiperimeter = (a+b+c)/2
