The area of the triangle can be calculated through the equation,
             A = sqrt ((s)(s - a)(s - b)(s - c))
where A is area, s is the semiperimeter ((a + b + c)/2), a, b, and c are the sides given above.

The presented equation above is the Heron's formula.

Substituting the known values,
             s = (8.7 + 10.1 + 9.8) / 2
              s = 14.3

    A = sqrt ((14.3)(14.3 - 8.7)(14.3 - 10.1)(14.3 - 9.8))
           <em>A = 38.9 units squared

</em>
Thus, the answer to this item is not among the choices. <em>
