Name the lenghts of the sides of three rectangles with a perimeter of 12 units use whole numbers only. I don't understand the question

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?
