Perimeter = 2 x (width + length)

⇒ 12 = 2 x (width + length)

⇒ width + length = 6

⇒ the rectangles could be:

- 1 by 5
- 2 by 4
- 3 by 3

[A square is a rectangle with equal sides.]

Q: What are the lengths of the sides of 3 rectangles with a perimeter of 12 units only whole numbers?

You can't tell the dimensions from the perimeter. There are an infinite number of different rectangles, all with different lengths and widths, that all have the same perimeter.

The sum of the lengths of the sides of a polygon is called the perimeter.

There are an infinite number of rectangles with this perimeter. The "whole number" sides could be (5 x 1), (4 x 2) or (3 x 3), but (5½ x ½) or (3¼ x 2¾) etc would fit the description.

If those numbers are the lengths of the sides, just add them.
