A square piece of metal measures 56 inches on one side. How many square feet are contained
within the piece of metal?​

Answer 1

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.

$area=(length)^{2}$

$A=56^{2}$

$A= 3136\ inches^{2}$

$1\ in^{2} = \frac{1}{144}\ ft^{2}$

Now, we divide area by 144 for feet.

$A=\frac{3136}{144}$

$A=21.78\ feet^{2}$

Therefore, the piece of the metal is contained 21.78 square feet.
