Step-by-step 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\times d\\\Rightarrow 1600=A\times 4\\\Rightarrow A=400\ ft^2

This area can be written as

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

10.2 ft Ans.

We solve this using geometric series.

A1 = 12 ft
A2 = ?
A3 = 8.67ft
Now, for geomteric progression,

\frac{A1}{A2} =  \frac{A2}{A3} 




\frac{12}{A2} = \frac{A2}{8.67}

A2 * A2 = (A2)^{2}  =  \sqrt{12 * 8.67 } 
 
A2 = 10.2 ft
