A triangle has si

Answer :

Let the sides be a, b and c


sides of triangle area = 35cm, b = 54cm, c = 61cm.


by Heron’s formula, we get the area of a triangle


=


(where s = s is called as the semi perimeter)…(1)


we get


Substituting the value of s, a, b and c in equation 1 we get



=


=


The area of a triangle is .


Find the smallest altitude,


The smallest altitude has the largest base.


The side which is largest has the smallest altitude.


largest side = base = 61 cm


Now the area of a triangle having base and altitude is given by


=


=
