Answer :

Okay, here we have this:

Considering the provided information, we are going to calculate the surface area of the pyramid, so we obtain the following:

Let's use the following formula to find the surface area:

Surface area=Area of the base+1/2*Perimeter of the base*Slant Height

Replacing:

Surface area=(12.2ft¨* 12.2 ft)+1/2 * (12.2 ft * 4) * 9.5ft

Surface area=148.84 ft² + 1/2 * 48.8 ft * 9.5 ft

Surface area=148.84 ft² + 231.8 ft²

Surface area=380.64 ft²

Finally we obtain that the correct answer is the first option.
