Answer:
C. 144 square feet
Step-by-step explanation:
step 1
we know that
The perimeter of a square is given by the formula
[tex]P=4a[/tex]
where
P is the perimeter
a is the length side of the square
we have
[tex]p=48\ ft[/tex]
substitute in the formula
[tex]48=4a[/tex]
solve for a
divide both sides by 4
[tex]a=12\ ft[/tex]
step 2
Find the area
The area of a square is given by the formula
[tex]A=a^2[/tex]
we have
[tex]a=12\ ft[/tex]
substitute
[tex]A=12^2=144\ ft^2[/tex]
