# The semi-perimete

Let the sides of the triangle be a, b and c.

Given that Semi-perimeter = s = 132cm.

Also, a product of the difference of semi-perimeter and its respective sides are 13200 cm2.

i.e. s(s – a)(s – b)(s – c) = 13200

we know by Heron’s formula.

Area of a triangle with sides a, b, c, and semi-perimeter s is given by

=

Substituting s and in above equthe ation we get

=

= 1320 cm2

The area of a triangle is 1320cm2.
