What rectangles have a perimeter of 52cm if both the length and width are whole numbers?[hint:there are 13 rectangles]
------
Perimeter = 2(length + width)
----
52 = 2(length + width)
----
length + width = 26
-------
Rectangles::
length = 1; width = 25
length = 2; width = 24
...
...
length = 11; width = 15
length = 12; width = 14
length = 13; width = 13
