<h1>16: So the first thing I did was examine the picture…take some mental notes and the like. Alright. So, I see that for every 2 L’s there is 3 W’s. That is important. So, I find out the current dimensions of the figure in terms of L. That would be 2/3L+L (width)*2L (height)=3.33…L</h1>
<p>3.33 equals 3+1/3…so, there’s your mixed fraction.
Now how many of these patterns do we need to get to 120L^2?
If 3.33 (3+1/3)=1 pattern, just set up a cross multipication deal.
3.33x/3.33=120/3.33 (I used fractions, and just multiplied by the reciprocal, by the way, but for simplicity’s purpose, I’ll use the decimals).
So I find out I need 36 patterns to achieve 120 L^2.
Cool.
Except I don’t need how many PATTERNS - I need how many rectangles. heh, so the first pattern has 5 rectangles, I need 36 patterns…
36*5=180; E.</p>
