Area ≈ 7.94
Explanation:
This is a 2 step process
step 1 : calculate ( half of the perimeter (s) ) of the triangle
step 2 : calculate the area (A)
let a = 6 , b = 4 and c = 4
step 1 : s =
(a + b + c )/2 = (6 + 4 + 4 )/2 = 14/2 = 7 step 2 : A
= sqrt(s(s-a)(s-b)(s-c))
= sqrt(7(7-6)(7-4)(7-4))
= sqrt(7 xx 1 xx 3 xx 3) = sqrt63 ≈ 7.94
