Pyramid abcde is a square pyramid. what is the lateral area of pyramid abcde ?

The lateral area of the pyramid is given by:
 A = (4) * (1/2) * (b) * (h)
 Where,
 b: base of the triangle
 h: triangle height
 Substituting values we have:
 A = (4) * (1/2) * (16) * (8 * tan (60))
 A = 443 in ^ 2
 
 the lateral area of pyramid ABCDE is:
 A = 443 in ^ 2

I’d say letter a..
