Question

Can someone explain Heron’s formula for area of triangle to me

Answer 1

s=a+b+c/2

area of triangle=

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

Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths. Therefore, you do not have to rely on the formula for area that uses base and height.

Answer 2

Answer:

Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.....

when the height of triangle are not given...we find the area of triangle through this formula....

where the formula is..

√s(s-a)(s-b)(s-c)

s is semi perimeter

s = a+ b+ c/2

and a, b and c is sides of triangle...

hope you understand this....
