how do you find an area of a triangle???????

Question

its for math i forgot how to find it lol

Answer 1

the base x the height, divided by 2.

if you don't know the height, it's not the side of the triangle, unless it's a right triangle.

use a^2+b^2=c^2 to find the height.
and don't forget to square root your answer.

Answer 2

1/2 base x height

Answer 3

This depends on what information you already have.
If you have one side and the altitude (height) to it, then it's
area = 1/2 base * height
as others have already said.
If you have two adjacent sides and the angle between them, it's
area = 1/2 s1*s2*cos(angle)
If you have all three sides, let s = (a+b+c)/2 (semiperimeter)
area = 1/2 sqrt(s (s-a) (s-b) (s-c))

I expect that those will cover whatever you're doing this week.

Answer 4

I think You times All the sides together Then divide by 2 Eg.
12x15x13 divide by 2

Answer 5

(lxh)/2
