Assuming you mean a square pyramid with base side length 5 and slant height 4:
Surface area = base area + lateral area
= s^2 + (1/2)(perimeter of base)(slant height)
= 5^2 + (1/2)(4·5)(4)
= 25 + (1/2)(20)(4)
= 25 + 40
= 65 square units.
If the base is not square (or you meant a different pyramid), tell me the base shape and dimensions and I’ll recalc.
