Let's assume that the width of the pool is represented by x. Therefore, the length of the pool is x + 20.
The perimeter of a rectangle is given by the formula: 2(length + width).
Substituting the values into the formula, we get:
2(x + 20 + x) = 160
Simplifying the equation, we get:
2(2x + 20) = 160
4x + 40 = 160
4x = 120
x = 30
Therefore, the length of the pool is x + 20 = 30 + 20 = <<30+20=50>>50 meters. Answer: \boxed{50}.
The perimeter of a rectangular pool is 160 meters. The length of the pool is 20 meters more than its width. What is the length?
