Heron's Formula = s(s-a)(s-b)(s-c)

given c = 5cm, a = 7cm, b = 10cm
so s = a+b+c/2
= 5+7+10/2
= 22/2
= 11
so area = √s(s-a)(s-b)(s-c)
A = √11(11-7)(11-10)(11-5)
= √11×4×1×5
= √220
=2√55
so s = a+b+c/2
= 5+7+10/2
= 22/2
= 11
so area = √s(s-a)(s-b)(s-c)
A = √11(11-7)(11-10)(11-5)
= √11×4×1×5
= √220
=2√55
