2. In geometry, Heron's formula, named
after Hero of Alexandria, gives the area
of a triangle when the length of all three
sides are known. Unlike other triangle
area formulae, there is no need to
calculate angles or other distances in the
triangle first.

4. Heron's formula, formula credited
to Heron of Alexandria (c. 62 ce) for
finding the area of a triangle in terms of
the lengths of its sides. In symbols, if a,
b, and c are the lengths of the sides:
Area = Square root of√s(s - a)(s - b)(s -
c) where s is half the perimeter, or (a + b
+ c)/2
5. Heron of Alexandria, also called Hero,
(flourished c. ad 62, Alexandria, Egypt),
Greek geometer and inventor whose writings
preserved for posterity a knowledge of the
mathematics and engineering of Babylonia,
ancient Egypt, and the Greco-Roman
world. Heron's most important geometric
work, Metrica, was lost until 1896.
6. Hero of Alexandria was a Greek
mathematician and engineer who was
active in his native city of Alexandria,
Roman Egypt. He is often considered the
greatest experimenter of antiquity and his
work is representative of the Hellenistic
scientific tradition.
Born: 10 AD, Alexandria, Egypt

7. Some examples of
the quadrilaterals are square,
rectangle, rhombus, trapezium, and
parallelogram. The area of a polygon
refers to the space occupied by the flat
shape. It is the combined sum of
the area of the regular and irregular
triangles within.
