Question

SOLVE IT USING HERONS FORMULA WHERE ... A=15
B=15
C=12

Answer 1

Answer:

In herons formula firstly we add all numbers which given and divide by 2

Step-by-step explanation:

15+15+12/2=42/2=21

Then put in formula, under root s(s-a) (s-b) (s-c)

Under root 21(21-15)(21-15)(21-12)

Under root 21(6)(6)(9)

Under root 21*6*6*9=under root 6804=82.48636
