Question

Antonio is building a deck around his pool. The pool measures 9 feet by 12 feet, and he wants the deck to have the same width on all 4 sides of the pool.

Answer 1

So, Antonio would be building a deck around his pool that has dimensions of 18 feet by 15 feet, with a 3-foot wide deck on all sides.

Let's say the width of the deck is w. The dimensions of the pool, including the deck, will then be:

1. Length: 12 + 2w feet

2. Width: 9 + 2w feet

This is because the deck extends w feet on each side of the pool.

If Antonio wants the deck to have a specific width, he can choose a value for w accordingly. For example, if he wants the deck to be 3 feet wide, then:

1. Length of the entire area =
`\(12 + 2(3) = 18\)` feet

2. Width of the entire area =
`\(9 + 2(3) = 15\)` feet
