Solution
Note: Formula For Finding the Area of A Triangle
[tex]Area=\frac{1}{2}absinC[/tex]
From the question, we have
[tex]\begin{gathered} a=9ft \\ b=15ft \\ C=110^{\circ} \end{gathered}[/tex]
The Area of the triangle will be
[tex]\begin{gathered} Area=\frac{1}{2}\times9\times15\times sin(110) \\ \\ Area=63.4292519 \\ \\ Area=63.4ft^2\text{ \lparen to the nearest tenth\rparen} \end{gathered}[/tex]
