2-18.

How many different rectangles can you draw with an area (number of “tiles”) of $28$? What is the perimeter (number of “toothpicks”) of each one? Show your work.

Here, an example has already been constructed. This is a $4$ by $7$ rectangle with a $22$ unit perimeter.

Use the eTool below to click and drag the tiles to form rectangles with differing dimensions. Remember, a rectangle has two pairs of parallel sides and four right angles.
