Question 692837
Set-Up
--------------
L = length
W = width
P = perimeter

The equation for the perimeter of a rectangle is: {{{P = 2L + 2W}}}

We were given W = 27ft & P = 134ft
Plug those values into the equation.
{{{134 = 2L + 2*(27)}}}
Simpify
{{{134 = 2L * 54}}}
Subtract 54 from both sides
{{{80 = 2L}}}
Divide both sides by 2
{{{highlight(40 = L)}}}
The length of the pool is 40ft
