Answer:

<h2>43.3cm²</h2>

Step-by-step explanation:

Area of a Triangle = Base * Height * 1/2

Base = 5

Height = 4.33

Area of a Triangle = 5 * 4.33 * 1/2

Area of a Triangle = 10.825

There are four triangles.

Surface Area = Area of a Triangle * Number of Triangles

Surface Area = 10.825 * 4

Surface Area = 43.3cm²
