Hey friend ..!!! here's your answer
By using Heron's method
we need to find s
s = sum of 3 sides / 2
= 13 + 9 + 6/ 2
= 28/2
s = 14
by using heron's formula
Area of triangle = under root s (s - a) (s - b) (s - c)
= underroot 14 ( 14 - 13) (14 - 9) ( 14 - 6) cm
= underroot 14 × 1 × 5 × 8 cm
= underroot 560 cm
= 23.66 cm
So the area of triangle is 23.66 cm
