The number of square feet of carpet you need to buy is; 203 ft²
Total Cost of Carpet = $281.51
We are given;
Measurement dimensions = 11.75 ft by 17.25 ft
A) The number of square feet would be needed is the area of the carpet. Thus;
Number of Square foot = 11.75 * 17.25
Number of Square foot = 202.6875 ft² ≈ 203 ft²
b) From conversions, we know that;
1 sq. feet = 1/9 sq. yards
Thus;
203 sq.ft = 203 * 1/9 sq.yards = 22.56 sq. yards
Now, the cost of carpet is $11.49/sq yd and the sales tax is
do 8.6%. Thus;
Total Cost of Carpet = (11.49 * 22.56) + 8.6%(11.49 * 22.56)
Total Cost of Carpet = $281.51
