Is this multiplication? Can you also help me with the answer!?


Answer:
84,375 m^2
Step-by-step explanation:
We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).
Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.
Area of a square is length times width.
Total area = [tex]4\times(\frac{1}{2}\times 225 \times 75)+225\times225 = 84375 m^2[/tex]
