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

Question

amistre64 · Answer

sounds like a herons rule ....

austinl · Answer

I was thinking about that myself.

amistre64 · Answer

i hate herons rule :)

austinl · Answer

Nah, it is simple enough.

austinl · Answer

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

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

amistre64 · Answer

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

amistre64 · Answer

n = 14.8/sqrt(298)

area = 12.6n * 11.8/2
