We will have the following:

1.


\begin{gathered} A=(10)(12)(sin(55))/(2)\Rightarrow A=60sin(55) \\ \\ \Rightarrow A\approx49.1 \end{gathered}

So, the area of the first triangle is approximately 49.1 ft^2.

2.


\begin{gathered} A=(18.5)(25)(sin(20))/(2)\Rightarrow A=231.25sin(20) \\ \\ \Rightarrow A\approx79.1 \end{gathered}

So, the area of the second triangle is approximately 79.1 in^2.
