The area of a rectangular pool is 225 square meters.the width of the pool is 9 meters.

Find the length of the pool
= meters

Find the perimeter of the pool

= meters

To find the length of the pool, we use the formula for the area of a rectangle:

Area = length x width

We know that the area is 225 square meters and the width is 9 meters. So we can plug those numbers in and solve for the length:

225 = length x 9

Length = 225 / 9

Length = 25

Therefore, the length of the pool is 25 meters.

To find the perimeter of the pool, we use the formula:

Perimeter = 2(length + width)

We already know the width is 9 meters and we just found the length to be 25 meters. So we plug those numbers in:

Perimeter = 2(25 + 9)

Perimeter = 2(34)

Perimeter = 68

Therefore, the perimeter of the pool is 68 meters.
