Respuesta :

It would be 20 inches
Since 400=x^2
The square root of 400 is 20

By definition, the area of a square is given by:

[tex] A = L ^ 2
[/tex]

Where,

L: length of the sides of the square

Substituting values we have:

[tex] 400 = L ^ 2
[/tex]

Clearing the value of L we have:

[tex] L ^ 2 = 400
[/tex]

[tex] L = \sqrt{400} [/tex]

[tex] L = 20 [/tex]

Answer:

The length of each side of the rug is:

[tex] L = 20 [/tex]
