The questions is telling you that there are three possible rectangles whose perimeter is 12 units and whose sides are whole numbers in length.
The perimeter of a rectangle is given by 2(L+B).
So, this means that L+B = 6.
What whole numbers add up to 6?
1+5 = 6
2+4 = 6
3+3 = 6
And those are your rectangles. One has sides of 1 and 5 units, the second has 4 and 2 unit sides and the third is a square with a 3 unit side.

Each rectangle has a perimeter of 12 units.
P = 2L + 2W
12 = (2 * 4) + (2 * 2)
12 = (2 * 3) + (2 * 3)
Can you think of the possible dimensions of a third rectangle?
P = 2L + 2W
12 = (2 * 4) + (2 * 2)
