Answer:

$L=4√(15)\ m$

or

$L=15.49\ m$

Explanation:

we know that

Applying the Pythagorean Theorem in the rectangular pool

d^2=L^2+W^2

where

d is the diagonal of the pool

L is the length of the pool

W is the wide of the pool

we have

$d=16\ m\\W=4\ m$

substitute the given values

16^2=L^2+4^2

solve for L

$L^2=16^2-4^2\\L^2=240\\L=√(240)\ m$

simplify

$L=4√(15)\ m$

or

$L=15.49\ m$
