I’m missing which dimension is which and what kind of pyramid you have. Common interpretation: a square pyramid with base side 3 m and slant height 7 m. If that’s what you mean:
Formula: SA = base area + lateral area = s^2 + (1/2)(perimeter of base)(slant height) = s^2 + 2 s l.
With s = 3 m and l = 7 m:
SA = 3^2 + 2(3)(7) = 9 + 42 = 51 m^2.
If you meant something else (triangular base, the 7 m is the vertical height instead of slant height, or the base side is 7 m), tell me which and I’ll compute it.
