If one side of a rectangle is 2A + B, and the other side is A-B longer than it, the perimeter is 2A + B______ .

If one side of a rectangle is 2A + B, and the other side is A-B longer than it, the perimeter is 2A + B______ .

The length of the other side is: (2a + b) + (a-b) = 3A. The perimeter is [(2a + b) + 3A] × 2 = 10A + 2B
