27 cm^2

Step-by-step explanation:

The surface area of this pyramid is given by this formula:

● Sa = area of the base + area of the sides *4

The faces are triangles.

The area of a triangle is:

● A = (b*h)/2

b and h are the base and the heigth

● A = (3*3)/2 = 9/2 = 4.5

The base is a square since all the sides are equal to each other.

The area of a square is:

● A'= a^2

a is the side

● A'= 3*2 = 9

■■■■■■■■■■■■■■■■■■■■■■■■■■

● Sa = A' + 4*A

● Sa = 9 + 4×4.5

● Sa = 27 cm^2

the correct answer to your question is a. 4^4
