area of a square equals the length of one side squared:

$a = {length}^(2)$

to find the length of one side:

length = √(area)

Plugging in:

length = √(144 ) = 12

Since there are 4 sides to a square we multiply the length of one side (12 inches) by 4 to see all the way around.

12 * 4 = 48

Sonya would need 48 inches
