A.) Here, Hexagon is represented by cutting two triangles from the rectangle, which makes 6 sides that what we know as a "Hexagon"
Dimensions: 7 ft, 20 ft, 6.40 ft, 6 ft, 14 ft, 10.77 ft
B.) Area = Area of rectangle - (Area of Triangles)
A = 24*11 - (1/2*4*10 + 1/2*4*5)
A = 264 - (20 + 10)
A = 234 Ft² [ Final Answer ]
Hope this helps!
