Answer:

$\boxed {\tt A= 81 \ ft^2}$

Explanation:

The area of a square can be found using the following formula:

A=s^2

where
is the side length.

We know the side length is 9 feet.

$s= 9 \ ft$

Substitute the value into the formula.

$A=(9 \ ft)^2$

Evaluate the exponent.

$A= 81 \ ft^2$

The area of the square is 81 feet squared.
