△ Find the area of the figure. ○ Find the area of the two triangles. ☼ The two triangles have a base of \(13.8 \text{ ft}\) and a height of \(9 \text{ ft}\). The area of the two triangles is \(2 \times \frac{1}{2} \times 13.8 \times 9 = 13.8 \times 9 = 124.2 \text{ ft}^2\). ○ Find the area of the central rectangle. ☼ The rectangle has length \(14 \text{ ft}\) and width \(13.8 \text{ ft}\). The area is \(14 \times 13.8 = 193.2 \text{ ft}^2\). ○ Find the total area. ☼ The total area is the sum of the areas of the two triangles and the rectangle. Total area \(= 124.2 + 193.2 = 317.4 \text{ ft}^2\). ✧ \( \boxed{317 \text{ ft}^2} \)

☺ \( \boxed{317 \text{ ft}^2} \)
