Question

What is heron's formula ​

Answer 1

Heron's formula gives the area of a triangle when the length of all three sides are known. Use Heron's formula to find the area of triangle ABC, if AB=3,BC=2,CA=4 . Substitute S into the formula . Round answer to nearest tenth.

Explanation:

Answer 2

`\boxed{A=√(s(s-a)(s-b)(s-c))}`

Explanation:

We can use Heron’s formula to determine the area of a triangle when three side lengths of a triangle are given.

`s=(a+b+c)/(2)`

`s : \mathrm{semi \: perimeter}`

`A=√(s(s-a)(s-b)(s-c))`

`A : \mathrm{area}`
