Draw a 3-cm-by-7-cm rectangle. Then discuss the difference in the units we attach to the 3 and the 7 in these two situations: When applying the rectangle area formula to determine the area of the rectangle, and when viewing the rectangle as decomposed into equal groups of 1-cm-by-1-cm squares in order to apply the definition of multiplication. Use drawings to support your discussion.

The length of a rectangle is 2 units more than the width. The area of the rectangle is 35 units. What is the width, in units, of the rectangle ?

Start with a square with side length $x$ cm. Imagine extending the length of one side to $7 \mathrm{cm} .$ a. What is the area of the original square? What is the area of the new, large rectangle? b. Use the areas you found to write an expression for the area of the striped rectangle. c. Now write expressions for the length and width of the striped rectangle. d. Use the dimensions from Part c to write an expression for the area of the striped rectangle. e. What do your answers to Parts b and d suggest about the expansion of $x(7-x) ?$
