The perimeter of tank is in the shape of square.
We have to find the side length of the base of the tank.
Perimeter of tank base = Perimeter of square =
[tex]P = 4a\\\text{where a is the side of square}\\60 = 4a\\\Rightarrow a = 15\text{ inches}[/tex]
Thus, the side length of of the base of the tank is 15 inches.
