Answer:

16 square inches

Step-by-step explanation:

First, find the area of the square.

Area of a square = width x length = 2 x 2 = 4 in²

All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.

Area of a triangle = 1/2 x base x height = 1/2 x 2 x 3 = 3 in²

So the total area of all 4 triangles = 4 x 3 = 12 in²

Therefore the total surface area = 4 + 12 = 16 in²
