Answer:

[tex]\boxed {\boxed {\sf 14 \ feet}}[/tex]

Step-by-step explanation:

To find the perimeter, you must first find the side length.

We are given the area. The formula for the area of a square is:

[tex]a=s^2[/tex]

We know the room's area is 196 square feet.

[tex]a=196 \ ft^2[/tex]

Substitute the area in.

[tex]196 \ ft^2=s^2[/tex]

We want to find the side length, so we must isolate s on one side of the equation.

  • s is being squared.
  • The inverse of a square is the square root.
  • Take the square root of both sides of the equation.

[tex]\sqrt{196 \ ft^2} =\sqrt{s^2}[/tex]

[tex]\sqrt{196 ft^2}=s[/tex]

[tex]14 \ ft=s[/tex]

Now, find the perimeter. This can be found using:

[tex]p=4s[/tex]

We know the side length is 14 feet.

[tex]p=4 (14 \ ft)[/tex]

Multiply.

[tex]p=56 \ ft[/tex]

The perimeter of the room is 14 feet.
