Answer:
1, 215
Explanation:
To calculate the cost of the cover, we need to know the area of the pool. Assuming that the pool is rectangular and has the dimensions given by the four numbers provided (30, 18, 18, 6), we can calculate the area as follows:
Area = length * width
Area = 30 * 18
Area = 540 square feet
Therefore, the cover for this pool would cost:
Cost = Area * Price per square foot
Cost = 540 * $2.25
Cost = $1,215
So the cover would cost $1,215.
