The second feature of your one million dollar pool complex is to have a designated kids pool with a concrete pad along one side of the pool; this way parents will have a nice area to lounge in the sun while watching their children swim. You have designated a total area of 5,000 square feet for the kids pool and the concrete pad. Due to the layout of the land/space you have available, you've determined that the length of the rectangular kids pool must be 30 feet greater than the width. The dimensions of the concrete pad are 20 feet by width feet, where width is the unknown width of the pool that aligns with the concrete pad. Use this information to determine the width of the pool (which is the same width as the concrete pad). Then determine the area of the concrete pad and the area of the kids pool.
