To determine

To find : The area of the square.

Answer to Problem 9PSA

The area of the square is $A=324$

Explanation of Solution

Given information : The radius of the inscribed circle is given as

  $r=9$

Formula used : We use the following formula to find the area of the square

  $A={\left(2r\right)}^2$

Calculation : Substituting the value of $r=9$ in the equation, we get

  $A={\left(2\times 9\right)}^2=324$

Thus, we get

  $A=324$
