<span>The problem says that Donovan is using similar rectangles, so you can calculate the length of the second rectangle, by using the similarity concept.
We have that the first rectangle </span>is 2 inches wide and 6 inches long, and the second rectangle must has<span> 5 inches wide. Then:
2/5=6/L (L: </span>the length of the second rectangle).
<span> 2L=6x5
2L=30
L=30/2
L=15 inches
H</span><span>ow long must the second rectangle be?
</span><span>
The answer is: The second rectangle must be 15 inches long.
