Answer
There are 9 square feet in a square yard.
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. In the diagram, we can see that a square yard contains 9 square feet.
