To cover the triangle shown in the figure, we consider the height of the triangle (8 ft tall) and the length of the base (24 ft wide).
______________________________________________
Since we are given that this is a "frame", this is a rectangular frame. The problems asks, how many (minimum number of) 8 ft x 4 ft. sheets are needed to cover the entire frame?
Since the entire frame is 8 ft. x 24 ft. , The answer would be "6", since:

24 ft ÷ 4 ft = 24 ft / 4 ft = 24 / 4 = 6 .
