Answer:
A.
Step-by-step explanation:
The area of the base is 21.16
You have a 30°60°90° triangle on the sides, and the leg opposite to 30° is 2.3
The height of the triangle is 2.3√3
The area of one of the triangles is 2.3√3 * 2.3 = 5.29√3
The area of all four triangles is 21.16√3
21.16√3 ≈ 36.7
Hope I'm not wrong.
