11. In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a
triangle by requiring no arbitrary choice of side as base or vertex as origin, contrary to other formulae for the area of a
triangle, such as half the base times the height. Use Heron's Formula to find the area, in square centimeters, of AABC.
