Answer:
The surface area of the rectangular pyramid can be calculated using the formula:
Surface area = (B + (4 x L))
Where B is the area of the base and L is the area of each side.
In this case, the area of the base is 14 x 17 = 238 in2 and the area of each side is 1/2 x 12 x 12.9 = 77.35 in2
Substituting these values into the formula, we get:
Surface area = (238 + (4 x 77.35)) = 441.3 in2.
Therefore, the surface area of the pyramid is 441.3 in2.
