Avantages of herons formula

Answer:
Heron's formula is a formula that helps you to find the area of a triangle when all you know are the lengths of the sides. It is an ancient formula that has been around for a couple thousand years!
Explanation:
First, we have a triangle with three sides.
To use this formula, the sides of a triangle should be labeled.
triangle with sides labeled a, b and c
We label our three sides a, b, and c. It doesn't matter which side is which as long as we have all three labeled in some way.
Next, we need to find half of the triangle's perimeter. We call this value s.
s = (a + b + c)/2
We find s by adding up all our sides and then dividing by two. The next part of Heron's formula gives us the area.
A = sqrt (s(s - a)(s - b)(s - c))
We see that we have to subtract each side from the half perimeter and then multiply all those values together along with the half perimeter again. Then, our area is the square root of our multiplication.
Answer:
The advantage is that the area is calculated using arithmetic operation and hence the time taken can be assumed to be constant
