Arectangle has a perimeter of 24 inches. what is a possible length and width for the rectangle?

The perimeter of a rectangle can be thought of as 2l+2w=p. That is, twice the length added to twice the width is equivalent to the perimeter. So a single length plus a single width equals 1/2 a perimeter. So, l+w=12.

Now find two numbers that add to 12 and you are done.

Here's an example:

Length: 7
Width: 5

Length:6
Width:4
The Reason I Say This Is Because 6x4 is equal to 24
