How to Find Heron's Formula?
The area of a triangle can be calculated by using Heron's formula if we only know the length of all three sides of the triangle.
Heron's Formula is given by A = √(s(s-a)(s-b)(s-c)), where 'A' is the area of a triangle, 's' is the semi-perimeter of half perimeter of the triangle, and a,b, and c are sides of a triangle and s = (a + b + c) / 2
Find the area of the triangle if the sides of the triangle are 3,4,5units?
Given: a = 3, b = 4, c = 5
s = (a + b + c) / 2
s = (3 + 4 + 5) / 2
s = 12 / 2 = 6
Heron's Formula is given by A = √(s(s-a)(s-b)(s-c))
= √(6 (6 - 3) (6 - 4) (6 - 5))
= √(6) (3) (2) (1)
= 6 square units.
Similarly, you can try the calculator to find the area of the triangle for
a) length of sides a = 6units, b = 7units, c = 8units
b) length of sides a = 13units, b = 12units, c = 11units
