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
