Answer:

48 square inches

Step-by-step explanation:

The area of the original rectangle is 8 * 12 = 96

The area of each of the small rectangles is 3 * 4 = 12

We know, 4 of these rectangles are cut, so area of 4 of these are:

12 * 4 = 48

The area of the remaining part, thus, is:

Area of remaining paper = 96 - 48 = 48 square inches
