Question

solve using herons formula
a=9
b=12
c=15

Answer 1

Answer:

THE HERONS FORMULA IS

$\sqrt{s(s - a)(s - b)(s - c)} \\ where \: s = a + b + c / 2$

Step-by-step explanation:

s=a+b+c/2

9+12+15/2

46/2

s=23

$\sqrt{23(23 - 9)(23 - 12)(23 - 15)} \\ \sqrt{23(14)(11)(8)} \\ \sqrt{23(1232)} \\ \sqrt{28336} \\ = 168.333003 {cm}^{2}$
