By definition, the area of a square is given by:
[tex] A = L ^ 2
[/tex]
Where,
L: length of the square side
For this case, the length of the square side is given by:
[tex] L = 9
[/tex]
Substituting values we have:
[tex] A = 9 ^ 2
A = 81 in ^ 2
[/tex]
Answer:
the calendar area is:
[tex] A = 81 in ^ 2 [/tex]
