# Thread: [SOLVED] Is this a trick question?

1. ## [SOLVED] Is this a trick question?

In the course of my trigonometry work I came upon a question that seems deceptively simple:

A triangle has sides, 18, 27, 36. What is it's area?

I'm betting that all I have to do is multiply 18*27 then divide by 2 resulting in an answer: $\displaystyle 243^2$
However, I have a feeling that I might be missing a step or two, so am I not thinking this through enough, or am I just looking to hard?

2. Hi there, have a go at Heron's formula

$\displaystyle A = \sqrt{s(s-a)(s-b)(s-c)}$ where $\displaystyle s= \frac{a+b+c}{2}$

Heron's formula - Wikipedia, the free encyclopedia

3. Ah......
Thank you!
I feel rather dim , but very grateful.

Don't, everyone starts somewhere. Asking for help is not an easy thing to do, so you should feel proud now that you know a new method.

There is not one mathematician that knows everything about Math, we are all always learning new things.

5. I really appreciate the encouragement, Pickslides-needed that!

Math is..... yet to become one of my better skills.

Now if you ever need help with writing or organic gardening....

Thanks for all you do here!
