See the attachment. I find it easier to split up the deck as such. We can now take areas of these 4 new rectangles that we made that we can find the dimensions for easily.
Left rectangle: 4*33 = 132 feet
Right rectangle: 4*33 = 132 feet
Top rectangle: 4*15 = 60 feet
Bottom rectangle: 4*15 = 60 feet
Add up all these areas to find the total area of the deck:
132 + 132 + 60 + 60 = 384 feet total.
This is answer C.
