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.
