It says 9 in. Also find the perimeter and area. If y’all could help me out that would be great.

Answer:
P = 36 inches
A = 81 inches ^2
Step-by-step explanation:
This is a square so all the sides lengths are equal
P = 4s where s is the side length
P = 4*9 = 36 inches
A = s^2 where s is the side length
A = 9^2 = 81 inches ^2
Answer:
Perimeter: 36 inches
Area: 81 inches²
Step-by-step explanation:
Hi there!
1) Find the perimeter
Apply the formula for the perimeter of a square:
[tex]P=4a[/tex] where a is the side length
Replace a with 9:
[tex]P=4(9)\\P=36[/tex]
Therefore, the perimeter of the square is 36 inches.
2) Find the area
Apply the formula for the area of a square:
[tex]A=a^2[/tex] where a is the side length
Replace a with 9:
[tex]A=9^2\\A=81[/tex]
Therefore, the area of the square is 81 inches².
I hope this helps!
