Answer:
10x5 (LxW)
Step-by-step explanation:
1 centimeter in your drawing should equal to 5 meters of the pool.
The length is 50, so 50/5 (5 is in meters, and it is equal to 1 centimeter) equals: 10
The width which is 25 in meters, would be equal to 5 centimeters in your drawing
I don't know if i made my explanation clear but hopefully the answer helped.
