Using Heron's formula, you can calculate the area of a triangle if you know the lengths of all three sides. Given the ie triangle as input, calculate the area of the triangle using Heron's formula as follows: 1. s= half of the triangle's perimeter 2. area = the square root of s(sa)(sb)(sc), where a,b, and c are each sides of the triangle. Use the math function sqrt() for calculating the square root. Output each floating-point value with three digits after the decimal point, which can be achieved by executing cout fixed setprecision (3); once before all other cout statements. Ex: If the input for a,b, and c is: 3.04.05.0 the atitnit is cout fixed setprecision (3); once before all other cout statements. Ex: If the input for a,b, and c is: 3.04.05.0 the output is: The area of the triangle is: 6.000 19.16.1: LAB: Area of a triangle main.cpp 1. \#include 1. Hinnludn inmanim
