`a = 12.32, b = 8.46, c = 15.05` Use Heron's Area Formula to find the area of the triangle.
When the three sides of the triangle are known, its area can be solved using the Heron's formula.
where a, b and c are the length of the three sides and s is half of the triangle's perimeter.
The value of s will be:
`s= (a+b+c)/2= (12.32+8.46+15.05)/2=35.83/2=17.915`
Plugging the values of s, a, b and c to the Heron's formula yields:
Therefore, the area of the triangle is 52.11 square units.
