1. Original dimensions of the rectangle: \((2y) \times (y-7)\).

2. Remove a 1-inch by 1-inch square from each corner, which subtracts 2 inches from each dimension.

3. New length: \(2y - 2\).

4. New width: \(y - 7 - 2 = y - 9\).

5. The area of the remaining rectangle: \((2y - 2)(y - 9)\).

Answer:

(2y - 2)(y - 9)
