I'm sure you are familiar with this
formula 1 by 2 into B into H it is used
to find the area of a triangle if its
base and height are given have a look at
this triangle have you ever tried to
find out the areas of such triangles
this formula won't work here because the
altitude is not given the areas of such
triangles can be calculated using
Heron's formula and this is what we are
going to explore in this chapter in this
chapter you will learn to calculate semi
perimeter of a triangle calculate areas
of triangles and quadrilaterals using
Heron's formula do you know Heron's
formula is credited to agreed geometric
haran and it's proof has been given in
his famous book metric a' to know what
Heron's formula is and to understand how
to apply it to find the area of
triangles and quadrilaterals stay with
us and study this chapter
