Step-by-step explanation:
Since 3 side lengths are given, I assume that this figure is a triangle. The area of a triangle can be determined by using hero's formula.

⇒ s = Perimeter/2
⇒ a, b, and c = side lenths of triangle
<u>Replacing a, b, and c as the given side lengths:</u>

<u>Determining the perimeter of the triangle:</u>



<u>Determining the half of perimeter:</u>



<u>Replacing the value of "s" in the formula:</u>

<u>Evaluating the area:</u>
