Answer:
34 m x 18 m
Explanation:
No picture shown, but we can do it anyway. If one inch on the drawing is actually 4 meters, multiply each dimension by 4.
The actual length is (8.5 * 4) = 34 meters.
The actual width is (4.5 * 4) = 18 meters.
The actual dimensions of the pool are 34 meters long and 18 meters wide.
