Answer:
21.78 square feet
Step-by-step explanation:
Let A be the area of the square.
Given.
A square piece of metal measures 56 inches on one side.
So the length of the square is 56 inches.
We know that area of the square is.
[tex]area=(length)^{2}[/tex]
[tex]A=56^{2}[/tex]
[tex]A= 3136\ inches^{2}[/tex]
[tex]1\ in^{2} = \frac{1}{144}\ ft^{2}[/tex]
Now, we divide area by 144 for feet.
[tex]A=\frac{3136}{144}[/tex]
[tex]A=21.78\ feet^{2}[/tex]
Therefore, the piece of the metal is contained 21.78 square feet.
