Double the Fun
Suppose we want to double the dimensions of this rectangle. Draw your figure using as many different methods as you can. Explain your methods.

Extensions 
Test this conjecture: If the sides of a figure are doubled to produce a similar figure, the area and perimeter will also double. Investigate with 2dimensional figures and extrapolate your findings to 3dimensional figures.
