Answer:

Step-by-step explanation:

There is something wrong in the length. Bcoz ABC is not formed a triangle. Sum of two sides must be greater than 3rd one. Here 20+3.4<42

Otherwise for abc triangle u can use scalene triangle area formula

Area=√(s×(s-a)(s-b)(s-c)

Where s is semiperimeter and a b c are d sides of a triangle.
