You can not convert units with different dimensions. Square yards measure area(2 Dimensions) whereas linea feets(you are meaning in one dimensions). Only what you can do is convert yards into feet and square yards to square feet. How you can use conversion factors between the two units to accomplish that. 1 yard=3 feets. 1 square yard =9 square feet.
You can convert this if you know the width of the Linear Yard. If this is for WallCovering, assuming the bolt is 54. One 54 inch wide lineal yard = 13.5 square feet. In this way you can convert Linear Yard to Ft^2.
