How This Is Calculated

Rectangular Cross-Section: $$ A = BH $$ Rectangle Area

Hollow Rectangular Cross-Section: $$ A = BH -bh $$
Hollow Rectangle Area

Circular Cross-Section: $$ A = \pi \cdot {\left(\frac{D^2}{4}\right)} $$
Circular Area

Hollow Circular Cross-Section: $$ A = \pi \cdot \left( {\left(\frac{D^{2}}{4}\right)} - {\left(\frac{d^2}{4}\right)} \right) $$
Hollow Circular Area

I Beam Cross-Section: $$ A = 2 Bh + Hb $$
