Answer 1

Answer:

A

Step-by-step explanation:

Let's assume the first pool to have dimensions 3.0 by 2.0

The second pool being 2.1 times the first will have dimensions 6.3 * 4.2

The area of the first pool is 6.0 and that of the second is 26.46

making the area of the second pool 4.41 times that of the first.
