This one is a plug in and simplify question. The formula  for area of a triangle is $\frac{bh}{2}$ where b is the length of the base and h is the length of the height. So in this case:

$$A=\frac{bh}{2}=\frac{(6.6)(4.9)}{2}=\frac{\frac{66}{10}\frac{49}{10}}{2}=\frac{3234}{200}=16\frac{34}{200}=16\frac{17}{100}={16.17}$$
