Area of a Triangle when sides are given Solution

STEP 0: Pre-Calculation Summary
Formula Used
area = sqrt((Side A+Side B+Side C)*(Side B+Side C-Side A)*(Side A-Side B+Side C)*(Side A+Side B-Side C))/4
A = sqrt((a+b+c)*(b+c-a)*(a-b+c)*(a+b-c))/4
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Side A - Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
Side B - Side B is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
Side C - Side C is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit

What is Area of a Triangle when sides and perimeter are given?

The area of a triangle when sides and perimeter are given, also known as Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria which states that area of a triangle can be found when the length of all three sides are known. According to Heron, we can find the area of any given triangle, whether it is a scalene, isosceles or equilateral, by using the formula, provided the sides of the triangle.
