Answer 1

Answer:

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

Step-by-step 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,

$\sqrt{100}=s$

$s=10$

The side length of a square is 10.

10 is a rational number.

Answer 2

The square root of 100 is 10. It is a rational number.
