I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
As we know the surface area of a square pyramid is:
SA = + (2 × a × s), where a is the base length and s is the slant height.
Given information in the photo,
The base area of the square pyramid: =
= 4 square meters
The slant height is 3 meter, so the area of the 4 sides: (2 × a × s) = 2*2*3 = 12
=> the surface area of the square pyramid is: The base area + the area of the 4 sides
= 4 + 12
= 16 square meters
