Answer: 45ft.
Step-by-step explanation:
Let assigned the value of x to the unknown lenght.
Therefore, the Length = xft
The with is 1/3 of the length and this. = 15ft.
Now , to get the length, we equate both together and then solve for x .
1/3 of x = 15
x/3 = 15
To get x, we multiply both side by 3
x = 45ft
The of the pool = 45ft.
<h3>Annual percent growth is 4.37 %</h3>
<em><u>Solution:</u></em>
<em><u>The increasing function is given as:</u></em>

Where,
y is future value
a is initial value
r is growth rate
t is number of years
From given,
a = 5000
y = 9500
t = 1997 to 2012 = 15 years
r = ?
<em><u>Substituting the values we get,</u></em>

Thus annual percent growth is 4.37 %
