The semi-perimete

Answer :

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.
