Answer:
43.3 m²
Explanation:
The surface area of the pyramid can be calculated as 4 times the area of one face.
So, the area of one face is equal to:
[tex]A=\frac{1}{2}\cdot b\cdot h[/tex]
Where b is the base of the triangles and h is the height. So, replacing b by 5 m and h by 4.33 m, we get:
[tex]\begin{gathered} A=\frac{1}{2}\cdot5\text{ m }\cdot4.33\text{ m} \\ A=10.825m^2 \end{gathered}[/tex]
So, the surface area is equal to:
[tex]A=4(10.825)=43.3m^2[/tex]
Therefore, the answer is 43.3 m²
