If the side length of a square is 9ft, what is the area?

stepan [7]

Answer:

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

Step-by-step explanation:

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

$A=s^2$

where $s$ 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.

(9 ft)²= 9 ft* 9ft = 81 ft²

$A= 81 \ ft^2$

The area of the square is 81 feet squared.
