\begin{gathered} \text{Total area= square´s area + triangles´ area} \\ \text{squares area= }(9)\cdot(9) \\ \text{squares area= 81 ft}^2 \\ \text{Triangles area =2}\cdot\text{ (}((12.3)\cdot(9))/(2)\text{)} \\ \text{Triangles area =}110.7ft^2 \\ \text{Total area=81 ft}^2\text{ + }110.7ft^2 \\ \text{Total area=191.7}ft^2 \\ \text{The total area of the figure is 191.7}ft^2 \end{gathered}
