What is the area of a square pig pen that has a perimeter of 72 feet?

324 ft^2

Step-by-step explanation:

P = 4s  for a square where s = side length

72 = 4s

Divide each side by 4

72/4 = 4s/4

18 =s

The side length is 18

A = s^2 for a square

A = 18^2

A = 324 ft^2

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

4th option is correct xy=-10
