Answer:
Perimeter = [tex]16\sqrt{5}[/tex]
Area = [tex]80[/tex]
Step-by-step explanation:
To find the perimeter of the square, you can use the square perimeter formula, [tex]P=4a[/tex], where [tex]a[/tex] is equal to the length of one side:
[tex]P=4a[/tex]
[tex]P=4(4\sqrt{5})[/tex]
[tex]P=16\sqrt{5}[/tex]
Then, to find the area of the square, you can use the square area formula, [tex]A=a^2[/tex], where [tex]a[/tex] is equal to the length of one side:
[tex]A=a^2[/tex]
[tex]A=(4\sqrt{5})^2[/tex]
[tex]A=80[/tex]
Therefore, the perimeter of the square is [tex]16\sqrt{5}[/tex] millimeters and the area of the square is [tex]80[/tex] square millimeters.
I hope this helps!
