Question

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

Answer 1

Answer:

• $\pmb{324~ft^{^{2}} }$

Step-by-step explanation:

As we know that,

Perimeter of a square is 4a

where,

• a =side

so,

According to the question,

• perimeter of 72 feet

• 4a=72

• a=72/4

• a=18

Now we have to find the area.

as we know that,

Area of a square is a^2

where

• a=side

Hence,

• Area=18^2=324ft^2

Answer 2

Answer:

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
