Answer:
441
Step-by-step explanation:
The perimeter of a square garden is 84.
Each side must be equal because it is a square.
[tex]P=4s[/tex]
[tex]84=4s[/tex]
[tex]\frac{84}{4} =s[/tex]
[tex]21 = s[/tex]
Each side of the square garden is 21.
The area of a square is equal to
[tex]s^2[/tex]
[tex]21^2 = 441[/tex]
The area of the square garden is 441.
