What is the formula for the area of cross-section of pole body for rectangular poles?

• A. area of cross section of pole body = 0.98 * axial length of the pole * breadth of the pole
• B. area of cross section of pole body = 0.98 / axial length of the pole * breadth of the pole
• C. area of cross section of pole body = 0.98 * axial length of the pole / breadth of the pole
• D. area of cross section of pole body = 1/0.98 * axial length of the pole * breadth of the pole
