Explanation:

The diagram is not included:

18 ft x 10 ft = 180 ft^2

180 ft^2 * $ 3.19 / ft^2 = $ 574.20 for a rectangular pool cover

If it is triangular 1/2 * 10 * 18 * $3.19 = $287.10

To find the cost of the cover, we need to first calculate the area of the pool. The area of a triangle is given by the formula:

Area = (base x height) / 2

Substituting the given values, we get:

Area = (18 x 10) / 2
Area = 90 square feet

Now we can calculate the cost of the cover by multiplying the area by the cost per square foot:

Cost = Area x Cost per square foot
Cost = 90 x $3.19
Cost = $287.10

Therefore, the cover will cost $287.10. None of the answer choices match this result exactly, but the closest one is G) $258.54. However, this is not the correct answer.
