`a = 3.05, b = 0.75, c = 2.45` Use Heron's Area Formula to find the area of the triangle.

Given `a=3.05, b=0.75, c=2.45`


Heron's Area Formula `A=sqrt[s(s-a)(s-b)(s-c)]`


where `s=(a+b+c)/2`


`s=(3.05+0.75+2.45)/2=6.25/2=3.125`


`A=sqrt[(3.125)(3.125-3.05)(3.125-0.75)(3.125-2.45)]`


`A=sqrt[(3.125)(.075)(2.375)(.675)]`


`A=0.6129`


The area is 0.6129 squared units.
