How many square feet are there in a room that measures 15 ft 5 inches by 9ft 8 inches?

Answer 1

You can convert both to inches (no ft): 15'5'' is 185'', and 9'8'' is 116'', so multiply to get 185 x 116 = 21,460; since a square foot would be 12'' x 12'' = 144'' sq in. then you would divide 21,460/144 = 149.02777 sq ft

You could also just convert both to decimalized ft so 15ft 5in would become 15.41666 ft and 9ft 8in would be 9.66666 ft; multiply the two so 15.41666 x 9.66666 would also = 149.02777 sq ft
