9-51.

The area of a rectangle is ^{2}. If the length and width each grow four times longer, what will the new area be?

Make an example of a rectangle with an area of ^{2}.

Since the area of a rectangle is (base)(height), choose a base and height whose product is

Multiply the base and height by

Now find the area of the larger rectangle by multiplying the new base and the new height.
