Answer:
-3x^2y^2(2x^2y^3 + 5x - 3y)
Using the net, we see that the square pyramid breaks down to 4 equivalent triangles and a square. We can use this formula to solve for the surface area:
Sa=A(square)+4*A(triangle)
The formula for the area of a square is
A=l*w
A=7*7
A=49mm²
The formula for the area of a triangle is:
A=1/2b*h
A=1/2*7*12.2
A=42.7mm²
Now that we have the individual areas of the shapes, we can solve for the surface area.
Sa=A(square)+4*A(triangle)
Sa=49mm²+4*42.7mm²
Sa=49mm²+170.8mm²
Sa=219.8mm²
Answer=219.8mm²

hope this helps!
Umm not really sure but I'd go with A. You may need another source to double check my answer, I'm probably wrong.
