1 Answer

Answer :

Here is an algorithm to find the area of a triangle:

Accept the values of the three sides of the triangle (a, b, c).

Calculate the semi-perimeter of the triangle using the formula: s = (a+b+c)/2

Calculate the area of the triangle using the formula: area = sqrt(s(s-a)(s-b)(s-c))

Display the area of the triangle.

This algorithm uses the "Heron's formula" for finding the area of a triangle, which is based on the semi-perimeter of the triangle and the lengths of its sides. The semi-perimeter is simply half of the perimeter of the triangle, and it is used as a way to simplify the formula and avoid having to calculate the perimeter.
