Answer 2

The side length of a square is 10 and it is a rational number.

Explanation:

Given : A square rug has an area 100 ft squared.

To find : Write the side length as a square root. Then decide if the side length is a rational number ?

Solution :

A square rug has an area 100 ft squared.

The area of the square is
`A=s^2`

`100=s^2`

Taking root both side,

`√(100)=s`

`s=10`

The side length of a square is 10.

10 is a rational number.
