Question

Find the area of the triangle with a = 11.8, b = 12.6, c = 14.8. Round to the nearest tenth.

Answer 1

sounds like a herons rule ....

Answer 2

I was thinking about that myself.

Answer 3

i hate herons rule :)

Answer 4

Nah, it is simple enough.

Answer 5

It is a two step process,
1) We need to calculate "s", which is half of the triangle perimeter.

\(\displaystyle s=\frac{a+b+c}{2}\)

2) We can then calculate the area using a neat little formula!

\(A=\sqrt{s(s-a)(s-b)(s-c)}\)

Answer 6

lol, i swear i can find the hardest way to do the simplest tasks :)

Answer 7

It is a gift and a curse :P

Answer 8

okay, I'm working it out now. Thanks guys

Answer 9

i developed a right triangle with the given ab, and scaled it to the given c is all

Answer 10

n = 14.8/sqrt(298)

area = 12.6n * 11.8/2

Answer 11

I got 71.7
