If you find one wall is, say, 12 feet and 7 inches, then express this in feet by doing this: 12 + 7/12 = 12 + 0.5833 = 12.5833 feet If the other wall is 9 feet and 6 inches, then 9+6/12 = 9 +0.5 = 9.5 feet To calculate the area, multiply the two sides (expressed in feet) together: 12.5833 * 9.5 = 119.54 sq ft. Another way (ignore this if you think it will confuse the issue) is to convert everything to inches: 12' 7" = 12*12+7 = 144+7 = 151 in 9' 6" = 108+6 = 114 in Then the area of the room in square inches is 151*114 = 17214 sq in To convert this to square ft, divide by 144: 17214/144 = 119.54 sq ft. Once you have the area in square feet, say 119.54 sq ft, you can find the area in square yards by dividing by 9 (because 1 square yard is 3 feet by 3 feet, that is 9 sq ft): 119.54/9 = 13.28 sq yds. - Doctor Jerry, The Math Forum http://mathforum.org/dr.math/
