Exercise Sheet Number 6

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

Answer 1

21.78 square feet

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) = (1)/(144)\ ft^(2)`

Now, we divide area by 144 for feet.

`A=(3136)/(144)`

`A=21.78\ feet^(2)`

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