William was asked to draw two squares with the ratio of sides 2:5.
As you can see, each side of the original square is 1 unit, and each side of the new square is 2.5 units.
Can you find a way that William may have enlarged his squares?

$\text{William multiplied each side by 2.5, or }\frac{5}{2},\text{ in order to enlarge his square.}$

Do you think this will work for your rectangles? Make sure your drawings are neat!
