Answer:
20* 20, 16* 25, 10* 40

Explanation:

Given

The volume of the pool is
1600\ ft^3

Depth of water is
d=4\ ft

Suppose A is the base of the pool


\Rightarrow V=A* d\\\Rightarrow 1600=A* 4\\\Rightarrow A=400\ ft^2

This area can be written as


\Rightarrow A=10\ ft* 40\ ft\ or\\\Rightarrow A=16\ ft* 25\ ft\ or\\\Rightarrow A=20\ ft* 20\ ft
