In order to answer this, we need to know the formula of finding a perimeter.
By definition, perimeter is the sum of all the sides of a polygon.

The given is a square with a side length of 2 3/5 feet.

The perimeter of a square is 4S

Perimeter = 4 S
Perimeter = 4 (2 3/5)
Perimeter = 4 (13/5)
Perimeter = 52/5 feet

So the perimeter is 52/5 feet of 10 2/5 feet.
