Question

How do u find anarea of a triangle

Answer 1

half the area of a square with the same heigth and width

Answer 2

b*h*1/2 is the formula

Answer 3

or if it's not a right triangle, you can use

\[\frac{ 1 }{ 4 }\sqrt{(a+b-c)(a-b+c)(-a+b+c)(a+b+c)}\]

Answer 4

let the lengths of the sides a, b, and c
then semiperimeter
s=1/2(a+b+c)
Heron's formula gives the area of the triangle as

area=sqrt(s(s-a)(s-b)(s-c)).
OR else it is
area=1/2 base x altitude
