39 square inches

You need the area of the square base
Area = side^2
A = 3 x 3 = 9

And the 4 triangle sides.
Area of a triangle = 1/2(base)(height)
a = 1/2 (3)(5) = 7.5

We have 4 of those triangles on this shape
4 x 7.5 = 30

Add the triangles to the base for goal surface area
30 + 9 = 39 square inches

The correct choices are similar and same shape.

The two triangles have congruent angles and the sides are not congruent. Congruent angles make the triangles similar, which means they have the same shape. Since they do not have the same size, they are not congruent.
