Mr. Imaginary wants to build an island in the middle of his kitchen (see sketch above). The kitchen is 12 feet by 16 feet. A counter, which is 2.5 feet wide, goes around three sides of the kitchen. To meet Bangkok city permit requirements, there has to be 3 feet of clearance on all sides of the island.

Mr. Imaginary wants the island to be as large as possible. What is the maximum length and width, based on the information above? (Write your answer below)

1

What would be total area of floor space after the island is built? (The floor space is the tiled pattern in the sketch).
