Question

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

Answer 1

Perimeter: 36 inches

Area: 81 inches²

Explanation:

Hi there!

1) Find the perimeter

Apply the formula for the perimeter of a square:

`P=4a` where a is the side length

Replace a with 9:

`P=4(9)\\P=36`

Therefore, the perimeter of the square is 36 inches.

2) Find the area

Apply the formula for the area of a square:

`A=a^2` where a is the side length

Replace a with 9:

`A=9^2\\A=81`

Therefore, the area of the square is 81 inches².

I hope this helps!

Answer 2

P = 36 inches

A = 81 inches ^2

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
