Jim will have to pay $83.3 for an electric saw after discount.
4. A room is 5 ft. 6 in. by 9 ft. 9 in. wide. How many square yards of flooring are needed?
Converting the dimensions to inches:
5 ft. 6 in. = 66 inches and 9 ft. 9 in. = 117 inches
Area = 66 in x 117 in
Area = 7722 square inches
Area = 643.5 square feet
But they are asking for yards so we will have to divide 643.5 by 3.
A = 214.5 square yards
Therefore, you need 214.5 square yards of flooring .
