Answer 2

C) 17.1 square units

Explanation:

Use Heron's formula to calculate the area of the triangle:

`Area = √(s(s-a)(s-b)(s-c))` where
`s=(a+b+c)/(2)` which represents the semi-perimeter of the triangle:

`s=(9.9+6.1+6)/(2)=11`

Therefore:

`Area = √(11(11-9.9)(11-6.1)(11-6))\\`

`Area = √(11(1.1)(4.9)(5))\\`

`Area = √(296.45)\\`

`Area = 17.2`

Therefore, the closest answer choice is C) 17.1 square units
