Surface area of a rectangle is length x width.
Surface area of the roof = 35 x 12 = 420 square feet
Surface area of the floor = 10 x 6 = 60 square feet
Surface area of roof divided by surface area of floor = 420/60 = 7 times
Surface area of the roof = 35 x 12 = 420 square feet
Surface area of the floor = 10 x 6 = 60 square feet
Surface area of roof divided by surface area of floor = 420/60 = 7 times
