#### Answer

A square yard is 9 times greater than a square foot.

#### Work Step by Step

We know that $1~yd = 3~ft$
We can find the number of square feet in a square yard.
$1~yd^2 = 1~yd \times 1~yd$
$1~yd^2 = 3~ft\times 3~ft$
$1~yd^2 = 9~ft^2$
There are 9 square feet in a square yard. Therefore, a square yard is 9 times greater than a square foot.
