Which calculation gives the surface area of the rectangular pyramid?
\[
14 \times 4+2\left(\frac{1}{2} \times 2 \times \sqrt{245}\right)+2\left(\frac{1}{2} \times 7 \times \sqrt{200}\right)
\]
\[
14 \times 4+2\left(\frac{1}{2} \times 4 \times \sqrt{245}\right)+2\left(\frac{1}{2} \times 14 \times \sqrt{200}\right)
\]

Step 1 ：Calculate the surface area for both given expressions:

Step 2 ：Expression 1: \(14 \times 4+2\left(\frac{1}{2} \times 2 \times \sqrt{245}\right)+2\left(\frac{1}{2} \times 7 \times \sqrt{200}\right)\)

Step 3 ：Expression 2: \(14 \times 4+2\left(\frac{1}{2} \times 4 \times \sqrt{245}\right)+2\left(\frac{1}{2} \times 14 \times \sqrt{200}\right)\)

Step 4 ：Surface area for Expression 1: \(186.30\) square units

Step 5 ：Surface area for Expression 2: \(316.60\) square units

Step 6 ：\(\boxed{\text{The correct calculation for the surface area of the rectangular pyramid is Expression 2 with a surface area of approximately 316.60 square units.}}\)
