Answer:
Suzanne needs [tex]40\ ft[/tex] of fencing
Step-by-step explanation:
Step 1
we know that
The area of a square is equal to
[tex]A=b^{2}[/tex]
where
b is the length side of the square
In this problem we have
[tex]A=100\ ft^{2}[/tex]
substitute and solve for b
[tex]100=b^{2}[/tex]
square root both sides
[tex]1b=10\ ft[/tex]
Step 2
Find the perimeter of the square garden
The perimeter of the square is equal to
[tex]P=4b[/tex]
we have
[tex]1b=10\ ft[/tex]
substitute
[tex]P=4(10)=40\ ft[/tex]
