Question

3) The sides of a triangle are 5 cm, 5cm and 8 cm. What is its area?​

Answer 1

Answer:

I won't solve everything like calculation as you will not learn anything

√s(s-a)(s-b)(s-c) this is the Heron's Formula where everything is in square root

So s is semi perimeter which is half of perimeter=a/2+b/2+c/2

a=5,b=5 and c=8.
