Question

Find the area of the triangle ABC if a=37cm, b=25cm, and c=42cm

Answer 1

Do you know heron's formula?

Answer 2

Oh yeah.. A=\[\sqrt{s(s-a)(s-b)(s-c)}\]

Answer 3

That's what you should use here. Find semiperimeter by dividing the perimeter by two and then use the formula.

Answer 4

Do you know how to do it now?

Answer 5

Wouldn't I actually use S=(a=b=c)/2?

Answer 6

a+b+c+*

Answer 7

Yeah, that's what I said, perimeter is a + b + c.

Answer 8

gotcha! Thanks!
