Answer:

Area = 1053.59²

Step-by-step explanation:

Area = Area of cylinder + Area of rectangular prism

Area of cylinder = 2 π r h + 2 π r² [ r = 4, h = 8]

= 2 π r ( h + r)

= 2 π x 4 ( 8 + 4)

= 301.59 ft²

Area of rectangular prism = 2 ( 12 x 8 + 8 x 14 + 14 x 12) = 752 ft²

Area = 301. 59 + 752 = 1053.59²
